External HDD recognized in device mgmt not disk nor BIOS ...

Q: External HDD recognized in device mgmt not disk nor BIOS ...

Hello all,

After reading a lot of stuff and attempting fixes on my own (on three computers), I'm looking for help.

My external HDD Spire circa 2006 will not show up in Explorer; here's what I've done so far:

opened disk mgmt to partition it...not showing up in disk management
opened device mgmt ....shows up
disabled and luck
uninstalled and luck
updated driver .... "latest driver updated"

changed ports
changed computers (older version of windows)
restarted computers

on the third computer it shows as "working properly", but still does not show up in explorer. So...

opened CMD prompt
disk utility
list volume .... not showing up in list volume (as far as I can tell)

Does anyone have ideas? I'm not sure how I can fix any potential partition problems if it doesn't show up in disk management. I'm not sure if it's "working properly" why it won't show up in explorer.

I appreciate your help.


A: External HDD recognized in device mgmt not disk nor BIOS ...

Part of it has likely failed, hard drives fail all the time and externals fail even more often.

First try another USB cable. If that doesn't work take the unit apart and remove the actual hard drive. You can install the drive into another enclosure to see if it's the enclosure has failed. You could also install it internally in a desktop PC and see if it works instead of another enclosure. Being that old it might be either a newer SATA interface or it could be the older PATA interface with pins; if PATA you'll need an older computer to connect it to as new computers don't have PATA connectors anymore. I wouldn't buy another enclosure for it if there is not important data on it that you must recover, being that old it's simply not worth it to just get the drive working.

The equipment is good. Seagate 250gb SATA.

External Enclosure from Newegg:

It works flawlessly with any Vista computer. But on XP computers I get the same result; it is not recognized in my computer or disk management. If I fiddle with it enough I can get it to be recognized; uninstall drivers, reinstall them. restart, replug it in. Nothing is consistent, but sometimes it does indeed get recognized. But it's hard.

What happened originally was I bought it. Put it together. Installed the guy. And then I went to disk management and formatted it. I copied files to it. but when I turned it on and off it wouldn't be recognized! I plugged it into my roomates vista comp and it instantly came up and he copied files off of it.

Now I can't get it to come up in disk management or my computer EVEN though it is installed in the device manager and the safely remove hardware box comes up.

I've searched google for hours and no solutions. Please help me

also, when it is plugged in it takes my computer a really long time to boot.

My 2 yr old emachine laptop running XP is supposed to be plugNplay but it doesn't recognize a USB 120 Gig External Storage device when I plug it in. It recognizes flash drives fine, USB printer, and other devices tho. Just not large external storage devices (I've tried 3 different ones).

Thru some finnessing, I can get the drive to show up in Disk Management, and even access and transfer information to and from it, but it still wont show up in My Computer. All my USB ports work fine, and the External Storage devices pop right up when plugged into a desktop also running XP.

After searching other boards and trying other info, I've reset the BIOS, tried reformatting and re-partitioning the drives, but none of the suggestions have worked. It just wont show up in My Computer. It won't reformat giving me the error "The operation did not complete because the partition or volume is not enabled. To enable the partition or volume, restart the computer". Of course, restarting doesn't change anything.

The drives are showing up in Disk Management as Drives, and not as Removable Storage, so it isn't just a matter of "enabling" them.

Any suggestions? The tech support for the drive told me it was my computer's problem and the tech support for e-machines told me that it was probably because my laptop only has USB 2.0 ports, not Highspeed USB 2 ports. Yeah, right. OK, so basically they weren't any help at all.

A:External Storage drive in Disk Mgmt, but not in My Computer

I would say that you are definately correct in saying Emachines doesn't know what the hell they are talking about (I own one unfortunately). Also I would think that you need an update for the bios to support the larger usb drives but I'm pretty sure Emachines doesn't have one available yet. They are about a year behind when it comes to updates.

Just bought an acer aspire one netbook. (xp home)

Why is this happening?

A:USB device not recognized - external DVD drive

Is it a larger drive? Like desktop size? USB 2.0 won't be able to generate that kind of power. You may need to add the AC adapter. maybe even if it is laptop sized. Also I know you probably already did this, but make sure the drive is switched on, if it has a power switch.
Finally, some usb ports just don't play well with some devices. try a different port. if it still doesn't work, try plugging something else, like a usb mouse, into the same port, to check the port. I know it's rare but I have seen brand new stuff have issues.
My assumption is that the drive needs more power.

Last night I plugged into my computer my USB storage device to access some files and up came:


The computer had been on standby for an hour so I reckon this could be the problem but I tried all the remedies I could find: unplugged, switched off, leave for 5 minutes, reboot, etc. It did not work.

I've tried almost everything. So I went to bed and 8 hours later rebooted and plugged in my USB storage device and lo ah behold! "USB NOT RECOGNIZED"

So I phoned my dad and he said that I had to reinstall the chipset drivers and update the BIOS.

I don't like messing with the BIOS and I know nothing about installing any "chipset drivers".

Hello, all.

Very much out of the blue, my 160GB MyBook Essential Edition external hard drive from WD stopped showing up in My Computer. I tried it on my desktop and laptop, and I couldn't access the drive on either computer. I downloaded a diagnostic tool from WD's website, and the drive was found by the program and reported that the drive was working correctly. I later found the the Windows Device Manager also recognized the drive, and said that it was running with no problems. I'm afraid I may have deleted everything on the drive somehow, but I can't seem to find out if this is truly the case. I searched WD's site to find a download for drivers, installers, etc., but didn't find anything useful.

If anyone has any ideas about how I can regain access to my hard drive, I'd really appreciate it.

I have a Western Digital external USB hard drive, the 160gig model. I was watching a video from the drive and it got unplugged accidentally. Now whenever I plug it it in I get the following error in a bubble in the bottom right corner:

USB Device Not Recognized One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.

When I click the message, it displays a list of Unknown Devices attached to the Root USB Hub. Which in turn doesn't help me at all.

I have tried searching the web for drivers, used different usb cables, connecting it to my xbox360. Nothing seems to work. I can feel the drive spining on the inside and the lights signifying its on, but no soft response :(

If anyone has any helpful info on this or has experienced the same situation please let me know.

My WD Elements external hard drive was working great until one day it failed to be recognized in explorer. I've tried it on multiple PC's and it does the exact same thing. It shows up in device manager as properly working and also even shows up in devices and Printers and BIOS and Windows will allow me to eject it. I've tried using Recuva to recover my data but the disk still doesn't show up. I can't use CHKDSK because it doesn't have a drive letter. Is there anything I can do? and more importantly, is there any way I can recover my important data from this drive?

A:External hard drive not recognized on anything other than device mgr

Have you gone into the Disk Management tool to see if simply right clicking on the volume to change drive letter would initialze the drive again? The drive may be being seen as offline in the block on the left side of the item there you right click on to select the online option.

That would be a fast option included in Windows. Recuva wouldn't work without an active volume to begin with. When any Windows option won't work you then need an alternative option for data recovery such as a live Linux distro or other live from disk type. Note the 2009 thread for using a flash drive to make up a live data recovery disk. Using the "Other OS" For a USB Rescue Device?

The first thing however would be trying to see if you can get the drive initialized if it is showing up in the DM there. Often with removable drives and devices like flash drives or memory and memory cards SD cards on cell phones, digital cameras, etc. you need to keep a specific drive letter assigned to the drive or device to be instantly recognised each time you go to replug it in.

First of all, I'm new. Hello everybody and a have Great New Year.
Reading some posts in forums, I believe my problem is very common.
But I can't solve it.
I had an external case USB (2,5 without ext AC power) with HD 80 Gb. My old notebook Asus was short in HD so I used Acronis True Image to clone internal disk on external one, flagging "maintain old drive".
Then I opened the cases and I put the ext.disk inside and viceversa.
The Asus is OK.
But the ext case is no more recognized by PC.
When i plug in the USB cable, the disk run, PC tell me I've connected an USB dev., Device Mgr see the device (hard disk Hitachi bla bla), device flag is green, but Disk Mgt does not see it.
I tried TestDisk Utility to search for disk repairing: TestDisk sees the disk but does not see any partition any more.
I tried to use MBR write option in Test Disk or Partition Table rewrite option, but TestDisk says it can't read or write MBR and Partition Table.
Please help
I'd like to store the disk (it contain the original OS, if something goes wrong with the new disk installed ...)
Thank you

Hi Pinkfloydforeve and welcome to the TS Forum

I recently acquired a USB to IDE adaptor for work purposes, of course I took it home and played with it, it worked OK with a 20 and a 40 GB laptop drive, but did exactly the same thing as yours when I tried an 80GB 3.5" drive, figuring it to be a size issue I asked a collegue, who scratched his head (splinters) and said that he had no problems, in the end it was because the drive was set as CABLE SELECT, once set to Master the drive was seen in Disk management and I was able to format it Ok...

Is there jumpers on the drive you have put in the case, if so take them off or see if there is any legend to say how to set it to master...

Recently, for reasons I'm not sure of my external Hard Disk failed. When I plugged it in, it gave me "The disk is not formatted, Would you like to format it now?" error. It was recognized by XP and as a hard disk but with the label "Local Disk (F)" which was not its original name. Since I had important data on it, I resorted to a software called "Partition Table Doctor 3.5" to solve the issue. It told me that the partition table and some other things I can't really remember are all OK and if my drive still cannot be accessed by the OS, I had to use a file recovery software.

After that, I used EASEUS file recovery and used the complete file recovery option. It took several hours and when it completed, all the data was 'RAW' and there was no way I could use it. The next time I plugged my HDD in, Partition Table Doctor alerted me that the HDD had to be fixed. I did what it suggested and then it turned my HDD into a Removable Disk!!!

At this point, I gave up my hopes of recovering the data and tried to format the drive. Windows said it couldn't format the drive.

What can I do now?

Thank you

- In th disc management its not getting recognised.
- my laptop is recognising different hard disc drive and able to see the contents in it.

It's possible that the disk has gone bad or the controller inside the external enclosure has gone bad. One option would be to remove the drive from the external case and either install it in the PC or put it into another external enclosure and see if it works.

Later after abt half an hour I tried connecting back the hard drive to my same laptop, but it would not just show up. i tried everything liek trying to restart my system, connecting and disconnecting my external hard drive, changing the connecting USB cable, tried on different systems ( vista, XP) but the it would just not work( but the light on the hard drive does glow up).

The problem is pretty much sum'd up in the title. I have a 1TB Western Digital Blue Caviar sata HDD hooked up to the motherboard. A while back, when I went to go boot up the PC, the HDD busy light just stayed solid, and windows 7 took a lot longer than usual to load. When it does, I can't use the hard drive. I have tried to rescan for it in disk management and exhausted all most all the fixes I can find in threads on the net.

I know it's not a totally dead disk, because a couple times the C: drive (boot drive) automatically ran CHKDSK, it seemed to repair 1 or 2 small files, a file structure, or something, and then the D drive would return for a couple days before the problem returned.

I replaced the Sata cable with a new one, it started working again, but only for a few days. I'm kind of baffled on this one. Usually I figure these things out. Any help would be greatly appreciated. Have a good day.

You can use Macrium ( free) to create the image.
Be careful when downloading to always click "custom" and decline any of the crap it wants to add - i.e. changing search engines, home page, etc.

Make a boot cd( instructions on main page) and also after creating the image, do a Verify.

I do this by clicking Restore and browsing for the created image and you will see a link to Verify.

Put the image on a different internal hdd and if you have an external hdd, put one there as well.

Do an image backup periodically, (I do it once a week or after any major changes).

This will prevent loss of your files if you have a virus,corruption, etc.

I currently have 2 SATA hard disks connected, then 1IDE hard disk on blue IDE slot and 2 IDE cdroms on the other IDE slot. I also have two other external drives each connected to a USB port.

The problem is that the IDE hard disk is not being recognised in BIOS, when I try to switch some settings in the BIOS IDE configuration I have managed to get it recognised but then the cdroms are not recognised, how can I get them all recognised?

Another problem I have is with the external drives. If I switch them on before the computer boots up the POST will hang, so I have to leave them off until the POST ends and switch them on while windows loads so they get recognised by windows with all their sharing settings intact. Is there a way to eliminate this annoying problem?

I recently backed up about 500gb of recent work onto an external drive so I could clean my PC inside and out. I gave it a clean install of windows 7 and when it comes time to get my work of my external, the drive cannot be recognized and requires a reformat.

A:External disk not recognized by Win7/8 and is now in RAW format!?

Hi Mconn127,

I am not an expert in this field, just my experience offered.

Firstly, DO NOT FORMAT THE DRIVE!! (As your probably well aware) If windows ask you to do this when its plugged in then ignore.
The RAW filesystem is just a filesystem that is not recognized by Windows, so it cant access the disk and
as you found out your files are still intact..PHEW!!

I had the same problem a few years back when i just unplugged the USB HDD without "Safely removing Hardware device" first, and ended up with a RAW file system!!

Firstly try plugging the external HDD into a computer running Windows XP or Vista? Give that a try first if possible
and see if you can gain access to your data? With Windows XP theres a good chance you will gain access and can back-up your data and simply reformat the drive.(fingers crossed)

Failing that to try the next part you will need to discover exaclty type of external HDD it is? Make / model / aslo is it IDE, SATA and depending on which one it is, see if you are going to be able to connect it internally to your computer?

There is another way which doesnt involve opening the enclosure, but you risk losing your data and you do so at your own risk:

I have a brand new Foxconn A7GM-S 2.0 motherboad which seems to be unable to recognize my two SATA hard disks. I have ensured that the power connectors and SATA cables are snug, and have tried each pair of the six SATA slots on the motherboard. I also don't hear either hard disk powering up upon boot.

This board is a replacement for my older motherboard, which died rather suddenly.

Yesterday while watching movie on my PC it appeared as black on the screen and stopped working. After restarting the PC it was not responding as the BIOS was unable to recognize the hard disk. It creates an unusual sound while BIOS searches drives.

1. I tried by bootting the PC using another hard disk but this HD does not appear in the windows.
2. I also tried to boot using Ubuntu live CD but failed to find my HD on it.

As it is not recognized by BIOS, I cann't use data recovery software to recover the data. I'm badly in need of all data in it.

Please someone help me in this regard to recover the data.

Model: HD252HJ
Capacity : 250 GB
Interface : Serial ATA 3.0 Gbps

A:My Samsung Hard Disk is not being recognized by BIOS

Try the freezer trick. Place your hard drive in zip lock freezer bag to protect it from moisture and freeze it overnight (or a few hours at least). Quickly hook up the frozen hard drive and try to boot from it. If it works, be prepared to copy your important data as soon as possible before the hard drive warms up too much. This is not a permanent fix but it may work long enough to save your data.

Hi All,

I have an issue with the internal SATA HDD in my Pavilion dm4t laptop (PR #: XQ131AAR). The drive is working, when connecting via external USB enclosure is recognized by the PC, can read/write data, format partitions etc? When plugged in as internal HDD of the laptop, BIOS does not recognize it. When booting from Windows Installation Disk, the drive (and its partitions) are recognized, but I get the following message when trying to select a partition to proceed with Windows install:

Windows cannot be installed to this disk. This computer?s hardware may not support booting to this disk. Ensure that the disk?s controller is enabled in the computer?s BIOS menu.

Used external USB enclosure again, connected to a working PC and using TestDisk, I deleted the partition table (by zero writing it several times), then created a new MBR. When connecting back as internal drive, it is now recognized by BIOS and in the Windows installation screen, I can actually select a partition on the drive to install Windows on; the installation actually runs, but as soon as I get to the point of having to restart the PC during the installation process, upon restart the drive is not recognized anymore?

When I remove it, and repeat the same steps with TestDisk, it once again works, can start Windows installation, but it fails upon restart.

I have already read numerous forums on the topic, have tried various drive utilities. I also saw in one of the forums a suggestion to enable AHC... Read more

A:Windows cannot be installed to this disk... HDD not recognized in BIOS

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS. If UEFI follow these special steps for Install, otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install:

Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here. I would use a fresh ISO written with tool in Step 2 as yours is in question.

At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

SELECT DISK 0 (after confirming Windows 7 target HD #)

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failu... Read more

Hi all,

I know this is similar to at least one recent thread, but different enough to post.
I am upgrading my sister's machine from a 3.2Gb WD Caviar to a 40Gb Seagate U Series 5 drive, ST348023 from memory, ATA100.
The machine is running a K62 266, not sure of the Mobo, but obviously supports the AMD chip.
From what I have been able to glean from the Seagate site, this drive should be backwards compatible with any IDE connector, but when I stick it in, with the BIOS set to auto-detect all drives, the machine halts trying to detect the Seagate drive, although it will let me Ctrl-Alt-Del and also press Del to get into CMOS setup.
I have tried it as Primary Master, and as Primary Slave, both with the other HD on the same cable, and without it in at all.
Seagate's disk tools are able to detect that it is there, even when not setup in the BIOS. Seagate's disk wizard, which is an excellent tool for installing a new drive, told me that all I had to do was set BIOS settings to auto for that drive, and all would be rosy. It looks at what drive you have, what BIOS you have, and gives you instructions to suit. The documentation tells me that if the BIOS supports LBA and Large disk types, then all should be fine - it does.

Can anyone give me any ideas on what's going on? I have installed quite a number of hard drives in the past, but never come across anything like this.

Hi everyone
I'm new here and even though i have been reading a lot of usueful threads , i couldn't solve my problem at all.

I tried formatting it via windows but the proccess fails before even starting( it looks like any pc i connect it to, detect it at first(like a couple of seconds) but then its connection goes off even though its usb cable is perfect and i also tried connecting with several different cables just to be sure.

Then i used several programs, like "hard disk low level format tool" which as soon as i start the formatting process gives error strings and doesn't even start the process at all( remains stuck at 0%)

I also tried to use "Hard disk sentinel" program which gives it a status of 0% health and suggests me to back its data up. Too bad i just can't access it at all. it also states "REALLOCATED SECTORS COUNT"

I have a Simple Tech Pininfarina 320 GB external hard drive that is no longer recognized by two different PCs, even under disk management. When plugged into the USB, the PCs do try to install the driver, but fails. It is recognized under Devices and Printers as Unspecified and with the information Model-Simple Drive, Category - Unknown, and Status-Software is installing for this drive. The troubleshooter searches for a driver, but does not find one. Basically I get the information that "There is a problem wiht the driver for USB Mass Storage Device. Reinstalling the driver might fix this problem." But I cannot find a driver for this hard drive.

Can anyone steer me in the right direction?

Thanks in advance!

A:External hard drive not recognized in Disk Management

The system is telling you that there is a problem with a USB driver, check in the Device Manager for any yellow warnings. Under Universal Serial Bus Controllers you will see a driver for USB Mass Storage Devices, right click and uninstall it then reboot, Windows should reinstall it, or go to the motherboard's manufacturer's site and download and install the latest chipset drivers..

There are two other possibilities, the hard drive has failed or the circuitry in the enclosure has develpoed a fault.

Remove the hard drive from the enclosure and (if you have access to one) hook it up to the internal connections of a dektop PC. Or, purchase a USB Hard Drive Adapter (about ?10) from a computer store or eBay and then plug it into the USB connection on any computer and see if you can then access the drive.

I've been having this problem for a few months now. I recently built my own computer, having been on a lap top for a couple of years, and found my old external hard drive. I plugged it in to the new computer, and it said something about needing to be formatted, which I promptly did due to nothing of importance being on it. I went to sleep, and woke up to see that it couldn't be formatted.

This is where my issue begins. It no longer appears in Computer, or Disk Management. Disk Management won't even load if I have the drive plugged in. There seems to be no way at all to format the drive, since Computer, and Disk Management both don't load when the drive is plugged in. Any help?

Recently I decided to upgrade my hard disk storage space so I bought a Maxtor DiamondMax Plus 9 160GB SATA hard disk drive. Upon installing the drive I entered the Bios and went into "Intergrated Peripherals" section and set the BIOS to recognize P-ATA + S-ATA drives. When I reboot the new Maxtor drive shows up in Windows Explorer and functions normally. Also in Windows Explorer, my CD/DVD drive appears. However when I put a cd in the drive and click on the drive in Explorer I get the message to "Insert a disc into drive F:". The drive will not read the disc. When I went into Device Manager the CD/DVD drive shows up and says that it is functioning properly. Strange.....
So, I rebooted and reset the BIOS to the setup defaults (ie. P-ATA Drive Only) and when the computer boots up now the CD/DVD drive functions normally but the Maxtor drive is now not recognized. I understandObviously the Maxtor drive is not recognized because the BIOS is set for P-ATA drive only, but why when the BIOS is set for P-ATA + S-ATA is the CD/DVD drive not recognized?

Hello,Hope i'm putting this in the right section. My hard drive is supposed to be 320Gigs but is actually 300Gigs, & i have absolutely no idea where that 20Gigs went. Here's a quick background on where i think the space went to (but can't get back)...My computer came w/Vista 64bit when i bought it. Eventually, i decided to give Linux a shot... so i dual booted Debian & Vista (using GRUB as the BIOS & Debian as the default OS). Well, shortly after i decided i didn't like Debian & deleted it (& GRUB), & went back to Vista & the previous BIOS. Currently, my computer is working well... booting up fast as heck, never any issues, etc. I forget (lol) how i specifically got rid of Debian, but i know i used MBRFix along with reformatting the partitions back. Is it possible the 20Gigs is sitting somewhere but not identified by Vista for some reason?Screenshots - you guys have any idea where i could get the 20gigs back?Thanks in advance to anyone willing to help. I really do appreciate it.

A:Disk Mgmt : Used to have 320gigs, Now i have 300?

I'm no expert on these matters, but I think that's just the normal shortage that you get from hard drives. For example, my 250 gig external shows as a 232 gig. Although, my 300 gig internal does show almost 300 gig. Hmm. I've been no help at all, I'm sure. Ha. Here's what mine looks like, anyway.

Every time I open Disk Management is asks me to initialize a drive that isn't even there. I connect a bad drive as a slave, and it wouldn't initialize. now every time I open Disk Mgmt, it asks me to initialize the drive. I figure it is something in the registry I need to delete, but not sure of what.

A:Disk Mgmt ask to initialize a drive that isn't there.

From Microsoft:A basic disk's status is Not Initialized.

Cause:The disk does not contain a valid signature. After you install a new disk, the operating system must write a disk signature, the end of sector marker (also called signature word), and a master boot record or GUID partition table before you can create partitions on the disk. When you first start Disk Management after installing a new disk, a wizard appears that provides a list of the new disks detected by the operating system. If you cancel the wizard before the disk signature is written, the disk status remains Not Initialized.
So I believe you are correct in that Windows has created a registry entry for that drive without the Disk Signature in one of the keys.

You could try and find that key in a registry search if you search for the name of the hard drive manufacturer or serial number (a long shot, and it would be best to be the only drive in your system of that brand). You would need to be very careful to be sure you are not deleting a key for one of the other drives.

Or you could just click to initialize the (missing) disk and Windows might ignore it afterward. The danger here is that you would want to be sure that only the phantom disk is initialized, not a real disk. So you should disconnect any addition drives and only have your C: partition drive connected if you decide to try this. I've never tried it, but I don't believe Windows will allow you to initialize the syst... Read more

Backup whatever data you have on the 3TB drive, then all you have to do is format (initialize) the drive as GPT - the MBR standard only supports a maximum capacity of around 2TB - to use the rest of your hard drive, you need to use the newer GPT standard.

After that's done, your Hard Drive should appeaar with its full 3TB Capacity.

Hope that helps!

If it is showing up, try deleting the hard drive from device manager (make sure it is the right one!) and then perform the search. If that doesn't work let me know.

However, when plugged into the TravelMate, it does not boot from it. In the BIOS I have set boot priority to "Removable Device" then "CD drive" then "hard disk".

The reason I need the external drive in the first place is that the travelmate's cd drive is broken.

Windows cannot boot. There is a blue screen immediately upon startup. Only thing I can do is get into the BIOS.

Hi there, this drive is power fed trough the USB cable. So if the cable is damaged or too long it could cause the drive to malfunction. Otherwise it could be a damaged partition or a failed drive. I hope it will be a power issue, as it will be easier to resolve.
Have you tried:
- using a different USB cable (the shorter the better),
- connect it to a different usb port on the PC and make sure all other usb fed devices are unplugged at the time;
- if it's a desktop make sure to use a usb port that is on the back of the PC.
- connecting it to a different PC with a different OS

It will be useful if you give a bit more information. Can you hear any unusual noises from the drive? Have you dropped it recently? Do you remember making any changes before it stopped working ?

I've had this external hard drive for quite some time. It's a 230GiB Western Digital "Dual Option Combo External Drive".

Whenever I hook it up it adds the hard drive but when the time comes to eject it there's no remove icon available in the system tray nor is there an Eject command when I right click it on the explorer because Windows does not see it as a removable device but as a "permanent" device.

I don't know how long ago this happened or even if it was like this from the start. It's bugging me a lot because I don't know if I'm harming it by forcefully disconnecting the USB every time I stop using it. Here's an image of something odd about it:

What else can I try? I will try anything, but if it's hopeless, I need to know that too. I just don't want to give up if there's a chance!

Hello everyone,

A friend of mine bought a 3TB Seagate SATA drive off eBay about a week ago. He has been having trouble with it since. He said at first the disk showed up in disk management but after a while stopped showing up all together. It wont show up in the BIOS, device manager, etc. His brother took it to the IT faculty at school and they said that it was marked as a server/RAID drive but didnt know how to change this or reset it.

Should this effect whether the disk is seen by the BIOS/Disk Management?
Is there any way to fix this or is this disk shot?

He contacted the seller on eBay and has yet to hear back.

I have a PC which is having a lot of trouble recognizing a USB data acquisition device. Starting from a situation where the PC *does* recognize the device, here is the basic pattern:

1. PC shows device in Device Manager under "Data Acquisition Devices".

2. If the PC is power-cycled via the power plug itself, the device is no longer recognized under Device Manager ("Unknown Device").

3. If the PC is power-cycled via Start Menu --> Turn Off, same results as above, no longer recognized.

4. If the PC is power-cycled via Start Menu --> Restart, no problems, device recognized.

When the device is not recognized, unplugging and replugging the USB cable makes no difference to the situation. In order to correct the issue, I disable and then enable via Device Manager (which also involves a restart).

This pattern is extremely repeatable.

I am working with WinXP SP2, Pentium, 2.8 GHz, 504 MB RAM.

This PC was returned from a customer site - the PC and USB device are used in a machine my company manufactures. Apparently this issue just started happening one day. We want not only to correct the issue, but in fact to understand the root cause and ensure it will not happen again in the future.

Any suggestions would be greatly appreciated - thanks!

Johnwill's solution

Create a file with NOTEPAD containing the following lines and save it as FIX.REG
-------------------------- Use text after this line --------------------------------

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

-------------------------- Use text before this line --------------------------------

Double click on FIX.REG and say yes to the Merge Into Registry question.

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Disk Drives that you know are not present.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

Goto BIOS, there you have 4 options.

Set it as follows:

Primary Master -----> Main Boot HDD

Two of my USB external Hard drives, a Fantom 600 GB and a Western Digital My Book 500GB cannot be seen in My Computer. I can see them in Device Manager and that says that they are working properly and the drivers are up to Date. In Disk Manager the 2 external drives had a black bar unlike the other drives which had blue bars. The 2 external disks had a number assigned to them but no letter.

I have tried diskpart in the command prompt, was able to assign a letter, then had to format the drives and they did show up in My computer as valid empty external hard drives with the correct amount of space on them. But when I tried to recover the backed up data for one of the disks (less than a third of the capacity of either drive) they went back to not being recognized by My Computer ans in disk manager had a black line with no letter again.

I just went through that process again, got both drives back and tried to recover the backed up files to my Fantom drive and lost the Fantom drive once again.

I am attaching screen shots of my current My Computer (Computer in 7) Device Manager and Disk Manager. In Device Manager you can see the Fantom. The My Book is the WD 5000AAV.

A:External drives show in Device Manager & Disk Manager but not Computer

Hi Dick1030,

Welcome to Seven Forums.

Please do as follows:

1. It is unusual for the System Reserved Partition to have a drive letter. Please remove the drive letter.

2. Please remove (always Safely Remove) all the external drives including any card reader and do a drive cleanup as indicated here. It will clean your system of all non-present devices and you will be starting with a clean slate.(Incidentally this can resolve many drive letter assignment confusion of Windows OS, as you can see in the referenced thread.)

3. After you reboot on completion of the drive cleanup, plugin only your WD My Book and the Fantom drive. As you plug-in the driver for each device will be installed ab-initio. You can watch it.

4. Now take a screenshot of the Disk Management and post. While taking the screenshot, click on "Show/Hide Console Tree” and “Show/Hide Action Pane” buttons on the toolbar on top to hide those and also pull up the center partition line up as much as possible so that we get a clear and full view.

5. Also tell us whether you are sure that you had formatted the Fantom drive and it contains data and whether you want to recover the data..

(Your statements and the screenshots are so confusing - atleast to me - it is necessary that you do the above and restate the problem.)

Yesterday, I started a download and kept the pc on with my Seagate FreeAgent GoFlex External HDD 1TB plugged in. After I woke up I realized that there was a power cut and the computer went off unexpectadly (I had no UPS or any backup system).And, I found that my Ext HDD was not seen in my computer anymore (It was working perfectly until before I went to bed).
In device manager, under 'Disks' it shows 'GoFlex Hard Disk', but in BIOS or Disk Manager there is no sign of this HDD.

I really need the data in the HDD badly. Please help me recover it.
P.S. I read somewhere that keeping the HDD in freezer might help and give a little more time. Is that true? Worth the risk?

A:External HDD gets detected in Device Manager but not Disk Manager or seen in 'My Computer'

Power outage probably killed something in the enclosure or its PSU. The drive in the enclosure is probably fine. I would remove the drive from the enclosure and put it in a dock or install it in a desktop computer before considering freezing it. Freezing is usually reserved for click of death drives, and a last ditch effort.

Hello everyone,
i hope you can help me sorting out this issue that is causing me a hard headache at the moment.

I've bought this new Lenovo Z50-70 laptop with windows 8.1 preinstalled on it. Fresh new.

I'm trying to connect via usb a guitar audio interface (Line6 POD HD500) so i installed the drivers via the .exe setup file i downloaded from Line6's site.
The device worked fine on my previous HP pavilion with windows 7.

Now when i completed the installation, i connected it and i had this error:Windows has stopped this device because it has reported problems. (Code 43)A request for the USB device descriptor failed.
I used slimdrivers to update all the other drivers, in case it was a conflict causing the error.
I checked via command prompt with command "pnputil -e" and i saw a driver from the vendor of the device listed, so it is installed correctly i think.
I tried all USB ports i have, 3.0 and 2.0 on one side of laptop and 2.0 on other side.

When on device manager, if i click update drivers and choose the "let me pick from a list of device drivers.." i don't see the company name of the device.

i saw that another guy posted a really similar problem on SevenForum and he figured out how to force windows to use the drivers but he didn't post the solution.. Here is the post: Can't get Windows 7 x64 to use the drivers I've installed repeatedly Solved - Windows 7 Help Forums

Hello everyone..
Yesterday my laptop pushed a new Win 10 update, and all went fine, or at least I think so.
But today I see that my Sony WALKMAN - which I used with no problem until now, can't be recognized anymore.

Basically it just shows as (E or Usb Drive E: but when I click it it says "Please insert a disk into E:/" like there is nothing there.

Now the interesting part is.. if I go to Device Manager I see it and clicking on properties etc t says it's working fine.

But if I go to Disk Management, the Drive shows as 14 gb of unallocated space and it's greyed out.

However, if I put it on my brother's laptop, it works perfectly and it can be opened, music moved into it etc - it shows as Healthy - Primary Partition in Disk Management. So it doesn't seem broken...

It's the same on each of the 4 usb ports btw. But, other usb devices (2 phones, 1 tablet) don't have any issue and are detected.

What could have caused this? I tried the basic Disable/Enable in Device Manager and also Uninstall Driver.. It doesn't do anything, it appears back when I replug it in.

No change in Safe Mode and no change after sfc /scannow

If anyone has any idea I'd be happy to try anything to fix this..

I have an old PC (Compaq Presario Desktop 7470 ) that i purchased from a yard sale. I removed the old HD and replaced it with a quantum 30gb at Lct 20 HD that had Windows ME OS on it. I booted the pc and it booted fine except windows booted up in 16 bit color. I shut down and booted again. same thing. i shut down a third time and checked BIOS settings, then set them to default. Now BIOS doesn't recognize the HD or the CD-ROM drive. I have checked all connection, reset BIOS, removed the CMOS battery, I literally have tried everything I can think of to get things going on this old PC, but I am at the end of my rope. I will say that scandisk will recognize the HD and says it is OK. I have also taken the HD out and hooked it up to another PC and it boots up Windows ME just fine. I have also tried every jumper setting on the HD and Cd-rom to no avail and the only drive that shows up in BIOS is the 3.5 floppy drive which will boot up a Windows ME Boot Disk. I don't have a problem installing a fresh OS but want and need the PC to recognize the drives before i can do that correct?
I am ready to pull my hair out!! Can anyone please help me?!!!?

A:HD recognized by scandisk but HD not recognized by BIOS

probably the booting sequence is wrong due to the fact that you told the BIOS to load the preferred defaults. If you have a standard BIOS:

*go to advanced BIOS settings.... your going to see a big list of options .

<< check this picture for visual example>>
*take a look at the first , second and third boot device and change them to:

1- HDD - 0
2- HDD - 1
3- HDD - 2

Alternate them accordingly.

**probably the reason why your pc booted up at 16 bit the first time , may be
because you haven't installed the drivers for your video card yet.

It could be two unrelated issues.
1. You could have a device that needs a driver.
2. Some motherboards use a mixture of 1.1 and 2.0 ports, so that's the reason for the message.

You could check to see if you can get a hardware id for the device, from the device manager.

I have a Dell notebook, with what I believe is a USB 1.1 port on it. I recently bought a Microsoft wireless notebook optical mouse. There is no installation CD with it, you are just supposed to plug it in and it should work. Well when I do that, I get an error comes up saying USB device not recognized. When I look at the properties it says "no drivers are installed for this device", and I have the device usage as enabled. I've tried updating the driver and it says I have the most recent updates installed. It comes up as an unknown device as well.

Other things like my printer work in this USB port, so I don't think the port itself is defective. I also plugged the mouse into another computer and it works with no problems. I am running on XP with SP2 installed.

The product specs say it should work on USB 1.1 or 2.0, so I don't think that is the problem either. Any ideas? I've gone through all of the troubleshooting with no luck.

I am new to this forum and to posting tech questions online in general so hopefully I can describe what's going on accurately.

My computer has had no problems to speak of lately. I had not synced my iPod nano in some time, maybe a month or two, so I plugged it in yesterday to sync it. I received the following message: "iTunes has detected an iPod that appears to be corrupted. You may need to restore this iPod before it can be used with iTunes." I have since discovered the problem has nothing to do with the iPod itself. The iPod plays all the music and podcasts that are currently on it just fine. When I plug it into my girlfriend's computer, her iTunes recognizes it just fine as my iPod and I was able to pull videos off of it.

I am now pretty certain the problem is with my USB drives. I have an external memory drive that I use to back up documents - I had not used this in some time either. Out of curiosity I plugged it in, and it's not working either. When I plug it in and turn it on, nothing pops up, and when I try to do certain actions to check on it, like open My Computer, the system freezes and I end up having to manually shut down the computer and restart.

Here is my problem. Every Mass Storage device I put in the USB slots, came with the message USB not recognized...

It happened yesterday, when I plugged in the external hard disk into back USB slots. Hard disk works at other computer normally. Then I powered on my front USB slots (ther were turned off for couple of monts), put the phone, and it normally showed memory storage. Then I plugged hard disk into front slots, and it came with error. Then I again plugged phone in, but now I get the USB Device not recognizad, which is really weird, cause it worked a minute ago.

I tried every possible solution I googled, uninstalling SMS Bus Controllers, reinstalling chipset drivers and so on.

Weird thing is that Mass Storage devices aren't working on Windows 8 which is on the other partition within the same hard disk.

To mention, that all USB slots have normal power, hard disk is getting the power, phone is charging, Wireless Adapter is also working normally. I really don't know what could be the problem.

Is it possible that this hard disk could somehow insert some wrong data, because he is the source of this plague

Thanks in advance, waiting for suggestions

I have tried this USB on many computers and on different operating systems but the problem is same. I think its builtin plug and play driver is corrupted. I have my important data on it and I have to recover it. Please help me!!!!!

A:USB device not recognized

"I have my important data on it and I have to recover it"

Never, ever store important & irreplaceable data on just one drive, and especially if it's a flash drive as they are more prone to failure than hard drives (and unlike hard drives you don't get any warning). Flash drives are designed for short-term storage only (such as transferring files between computers).

It's not a driver issue if the same thing happens on other computers, because the driver is built-in to Windows (Windows XP and later) and they can't all be corrupted. The fact that the fault is constant on all computers proves that it's a faulty flash drive or it's simply worn out and needs replacing. Buy a well-known, reputable brand (Integral, SanDisk etc).

Normally I would recommend using some file recovery software to retrieve the data on it, but that requires the system to recognise the drive.
I can't think of any other way.

The drivers for USB 1.x are installed automatically by the operating system.
The drivers for USB 2.0, if your motherboard supports USB 2.0, are built into Windows 7 but the main chipset drivers for your motherboard must be installed.

What are your computer specs? Have you tried other ports?
Let's check out your device manager:

A:USB device not recognized


I have EXACTLY this problem on a Del Precision T1500 - Did anyone get back to you with a solution or did you solve your problem yourself?

Action Center is popping a steady stream - and I do mean steady - of "USB device not recognized."

Device Manager refreshes so often it is hard to right click on things because of the refreshing.

The item is listed as "Unknown USB Device (Device Descriptor Request Failed)." It alternates between these 2 error messages.

Device status:
Windows has stopped this device because it has reported problems. (Code 43)

A request for the USB device descriptor failed.

Device status:
Currently, this hardware device is not connected to the computer. (Code 45)

To fix this problem, reconnect this hardware device to the computer.

Greetings everybody,

I have a Removable Memory of over 200GB where I saved all my videos and photos plus other stuff. Recently, every time I go to My Computer, either I don't see any G or if there is, then all the items show empty folders. After I pluged and unpluged its USB and power cables, it usually worked. Today, however, I cannot make it work. Everytime, I plug it to the computer, I get a message saying:
"USB device not recognized. One of the USB devices attached to this computer has malfunctioned and windows dows not recognize it. For assistance in solving this problem click this message." I do click the msg but I don't get anywhere.

What do you think the problem could be? I am terrified of the possibility of losing years of photos and videos. This was supposed to work as my backup system!!

Your help is greately appreciatred,

A:USB Device not Recognized

Make sure your external drive is unplugged and go into device manage - scroll down to your usb ports and delete them. Reboot the computer and see if your OS, XP I assume, re-establishes your drivers for them. then plug in your HD and see if you can find your files. Luck Jazz

My mainboard is an Intel 440ZX 100Mhz. I have a P II 400. Also, I'm running Windows 98.

Anyhow, the mainboard has 1 PCI slot which has my 56K Motorola modem into it. The modem has a jack for a microphone (which is the only reason I need it, to use my mic).

I haven't used the modem in over 1.5 years since I have cable internet, so I don't know when my the modem became inactive.

Anyhow, when I went to Control Panel -> Systems -> Device Manager, I am told the PCI Communication Device is unknown, so I clicked the remove button (to remove the PCI device, hoping that the next time I reboot, Windows will notice the device and tell me to install it).

When I reboot, windows didnt' recognize it, so how can I get windows to recognize it? I opened up my PC and made sure the modem card is plugged into the slot correctly already.

Thanks in advance.

Windows is driving me nuts with this pop up message:

"USB Device Not Recognized. One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it."

When I follow instructions to fix the problem it says, "Try to reconnect the device. If Windows does not recognize it, replace it."

I don't have anything connected to the USB port they indicate and my system seems to be operating okay.

I just want to block the pop up message and move on. Clicking the close button only closes it for a few minutes, and then it pops up again.

I have a Dell Dimension 9150 and Windows XP Home Edition.

Until recently my usb scanner, camera and thumb drives (1,2 and 4GB) worked fine...about two weeks ago I started receiving the error message "USB device found" then "Installing your USB device" followed by "USB device is working properly" and then immediately afterwards the error message "USB device not recognized".

Within Device Manager it shows one controller as "Enhanced" so I'm assuming from what I've read that that means USB 2.0 drivers are installed. I've Googled the error message and followed several how-to's but still to no avail.

SP2 Q - how do I tell if I have it installed...within Add/Remove it shows many updates but nothing that says specifically SP2. I've downloaded SP2 but not sure I should/want to open that can of worms (after reading about program compatibilty problems)....any thoughts/suggestions would be appreciated.

1) None of my USB devices work.
2) Do I have Service Pack 2 installed?

A:USB device not recognized and SP2 Q...

Not absolutely certain, but I believe most older motherboards require Service Pack 2 to enable USB 2 support. The older Socket 939 motherboard I had required SP 2 to enable that support. The P35 chipset motherboard I have now has the support built into the motherboard. Follow this link for instructions on how to determine the service pack you have. If you do not have service pack 2 installed, I strongly suggest you download and install it. SP.htm

Good luck.

I have seen a few posts on this subject and I still can't get mine to work. My device is a Cirago 1TB mass storage device. It just stopped working and I have important files on there please help me as there are files on there that I need to run a website I own.

A:usb device not recognized.

Test it on another PC. That will determine if you have a PC issue or a faulty drive.

And I hate to point out the obvious, but you should have a backup copy of all important data.

Yesterday I was surfing on the internett when all of a sudden my mouse and keyboard malfunctioned. A small error message appeard from my system tray saying "USB Device Not Recognized". I don't know what could have caused this, but as I unplugged and plugged the mouse and keyboard back in they both worked again. When I use the computer for several minutes the same thing happenes again. Sometimes as I see the light go out from underneath my mouse I pick it up and it magically starts to work again, but there are still times when it doesn't start to work again just by waiting, and that's when I have to reinsert my USB devices to make them work again.

Anybody who might know what's causing this?

Hello guys, i recently bought a laptop and bought a mouse, speakers, etc, but suddenly, windows asked to restart, i restarted the laptop and when i turned it back on the Mouse wouldn't work anymore, flash drives won't work either, i did system restore and it wouldn't fix, i had to re-install the OS to get it working again, it did, now i turned off the laptop at night to go to sleep, and when i wake up and turn the laptop on, the usb units won't work again.

I already did going to device manager, uninstall everything under usb and restarted, but nothing happened.

Hope you can help me


A:USB Device not recognized


It sounds like the USB devices are going to "sleep" and not turning on again. Turn OFF selective suspend using this, and see if it helps.
