Change Drive Letter & Paths Greyed out

Q: Change Drive Letter & Paths Greyed out

I am still unable to access my WD 5000H1U external hard drive. It is showing in Device MGR & Disc Management. However when I access Computer it is not showing. When in Disc Management it is there ok but with no drive letter. Right click reveals drop down box but everything is Greyed out. The external HD is up and running ok with blue lights, I have even tried 3 separate USB cables but with no joy. I have checked the drivers and they are up to date...... When i first switched it on it did register ok in Computer but since then nothing. It works perfectly on my Apple laptop. I am running Windows 7 Home edition. Any help would be much appreciated. Lee

A: Change Drive Letter & Paths Greyed out

Has the drive been initialized?

To initialize new disksIn Disk Management, right-click the disk you want to initialize, and then click Initialize Disk.
In the Initialize Disk dialog box, select the disk(s) to initialize. You can select whether to use the master boot record (MBR) or GUID partition table (GPT) partition style.
Note The disk is initialized as a basic disk.

Additional considerations
New disks appear as Not Initialized. Before you can use a disk, you must first initialize it. If you start Disk Management after adding a disk, the Initialize Disk Wizard appears so you can initialize the disk.

I have a drive that has a lot of information on it that I need. A user left our company and all of his files are on this drive. I was handed it and asked to build a VM with all his information on it. When I plug the drive in it loads the drivers and shows
up just fine in Computer Management (shown below), but not in Computer. So I think, ok, I'll just add a drive letter but that option is greyed out and won't let me. The disk is initialized and appears to be healthy. I have gone to device manager and made sure
there were no problems there as well. It was also an external drive so I removed it and made it an internal drive on my machine but got the same results. It shows up in BIOS but obviously can't boot off of it since it is not an OS drive.
Deleting/formatting the drive is not an option. Is there a way to get this drive accessible without that? Deleting it is the exact opposite of what I want done here. 

A:Change Drive Letter and Paths... greyed out. Can't assign drive letter.

That looks like a mac formatted drive, that's why it wont work on your PC. Try installing Paragon HFS+ for Windows.

I lost my Event Viewer, and had to do a repair installation to fix it. Unfortunately, during the repair install, Windows decided to rename my second HD as the D: drive... it was K: before that. Now I cannot access any of my docs, pictures, music, or videos through the normal means... they don't show up in libraries or explorer, and apps like Restorator and Sure Thing (CD labeler) cannot find them. I think that means the paths are broken..?

It won't allow me to rename the HD back into K: (it's not listed as available). I can access the data by clicking Computer > D, and I can see the data is there, but its unusable as of now. Any ideas?

A:Can't change hard drive letter to needed letter

Hello Stevie,

To be safe, you should create a restore point before doing this in case you make a mistake and need to use it to do a system restore.

1. If the K letter is not being used by another internal drive, then you can open regedit and navigate to:HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
2. In the left pane, Take ownership (step 2 in Option Two of METHOD TWO) of the registry key MountedDevices and "Allow" yourself "Full Control" of it as well.

3. In the right pane of MountedDevices, right click on \DosDevices\K: and click on Delete and OK.

4. Restart the computer to apply. You should now be able to change the second hard drive letter to K.

Hope this helps,

i have windows 7 desktop. there are some partition on it.but there is problem with these partition. All the three partition have the same drive letter.i attach a link showing the picture. all three partitions are dynamic , simple. if i open these drives only the contents of one drive are appeared. another two drive data are not shown in any manner.

i don't want to lose any data from any drive ......
please help me sir...
my windows is installed in c:\ drive which is also dynamic and there are no recent changes.only one change i did which is i shrink dynamic volume 50 GB from 206 GB and again mixed with 206 GB without allocating free space.

and only the c drive is on and d drive is off.but in my other desktop same configuration exist.
please help me...and please don't say change and remove drive letter...........waiting for response

A:changing one drive letter all 3 partitions change to that drive letter

First thing you're going to do is fill in the specs of the desktop whose snips you are showing us.

Then you're going to do the same with the second pc opening a second post with snips. Give it a different title like "Second pc with drive letters the same". Don't forget the snips.

You should not have dynamic disks in either machine. What did you do to accomplish this?

There exists a bevy of spectacular experts on this site that will be happy to help you. But give us ALL the info please.

Hi everyone. Today I dual booted Windows 7 and Windows 8. Everything was fine, until I decided I wanted to point my music collection in Win8 to my Win7 music folder (turns out you can't do this right now anyway in the music app). I wanted to make sure that win8 didn't screw with any files so I changed the whole drive permissions in Win8 to have read access, but not write access of my Win7 drive. I did the vice versa for Win7.

When I restarted my system I got a "windows created a temporary paging file..." error message and figured out its because I screwed with my file permissions. To fix it I just need to change the permissions back, however now they are all greyed out (even in the (hidden) Administrator account) and I can't figure out how to change the permissions back.

Anyone know how to do this? Any help would be greatly appreciated.

P.S. Windows 7 decided to create this temporary paging file in another partition (about 500 MB in size) that was unused, which has full and unchanged permissions.

A:How to change drive permissions if options are greyed out?

Alright I figured out how to fix it. I went into disk management and made my C: the active drive (isn't it supposed to always be active? idk maybe it was turned off). Once I marked it to be active it allowed me to change the permissions back to what they were. Once I did that, I rebooted my machine and for some reason BOOTMGR got messed up (when I marked my drive as active I guess) and said it was missing. To fix this I just put my windows disc in the drive and used the repair startup option. Now everything works as it should. Thats the last time I screw with drive permissions.

I wish I can mark my own post as the answer. Oh well.

I have a USB external hard drive that I keep all my documents etc on (had it for years)

I upgraded from Vista Home to & Home Premium then had to upgrade recently to Professional to run my Sage. Through all these upgrades my ext. drive ran fine. Occasionally the drvie letter would change if I had something else plugged into the USB, this was always easily corected in disk management by changing the drive path.

The connection on the case packed up so I had to get the drive put into a new case, now when I plug it in the drive is assigned G instead of F, I tried to change the drive letter allocation in Disk Management but it won't let me as the program still thinks I have a second ext. hard drive which is labelled F. I suspect this has happened because when the usb connection broke the drive was disconnected suddenly instead of a proper eject.

How do I get Disk Management to remove the inactive drive - i can't find any obvious way - eject, delete etc are all missing when I click on tools or tasks.

If there is no easy way then how do I stop program updates for Adobe etc. failing because they can not find the F drive. I don't know why they look at that drive anyway.


A:External Hard Drive - Drive Letter changed - unable to change back


Welcome aboard.

Try this:

Download V 0.8.1 from

Drive Tools for Windows

Unzip to a folder. In it you will have two folders Win32 and x64, each containing DriveCleanup.exe for Windows 32bit and 64 bit respectively.

Now unplug all the USB devices from your PC (except of course the Keyboard and mouse), right click on the appropriate DriveCleanup.exe for your system and run it as an administrator.

This will remove all non-present drives from the registry.

Reboot and then plug-in your external drive.

The drive will be installed and hopefully you should be able to assign any free drive letter to it.

Please report whether it resolved your problem.

My External Hard Drive (My Book) was always Drive letter F.

I went to sleep and woke up to find Windows 7 Pro had updated and rebooted and I was welcomed by my login screen.

Consequently now my My Book external HDD now reads as Drive letter G.

I went into Administrative Tools > Computer Management > Disk Management

Drive letter F is not available.

F is assigned to a drive that does not exist and never has. I am confused. I only have one CD drive and it says now that I have 2 even though the one addressed as F doesn't have any information. If I click on F it says "Insert Disk"

Hi, new to these forums so I really hope I'm posting this up in the right subforum.

Long story: My old hard drive was dying, and after installing a new one I used this "EaseUS" program to clone the old HDD's data onto the new one. This worked fine except for the fact that all of my shortcuts stopped functioning because the letter assigned to the new HDD was different from the old HDD.

Is there any easy, automatic way of making all shortcuts point to the new file path? Or do I have to manually change the hard drive letter in each shortcut's properties?

Ok, here's the situation, I want to install XP Pro on a former XP HE (I say former because there are so many corrupt/damaged system files that no Win DVD, or live CDs can recognize it..), on a Vaio VGN-A617B laptop.
I would prefer to do a factory recovery from the recovery partition but there seem to be some problems too, it can't set up properly.

In short:
I got the error "unmountable drive" after a system crash.
After trying unsuccessfully to repair it with the recovery console doing chkdsk/fixboot/fixmbr, I tried to replace the files using the repair option on a Win DVD (not from the recovery console) but it couldn't see any previous Windows installations and only listed the partitions leaving me with set up/create/delete options.
I made a BartPE DVD to copy and save some personal files on an external drive.
Unfortunately, BartPE completely messed up the drive/partition letters and gave the letter E to the external drive, but E was the hidden vaio recovery partition, so C was assigned to it...
After restarting the laptop and unplugging the external drive, the vaio recovery partition kept the letter C, and E was given to the system volume...

So, now I am left with a laptop that tries to boot from the unworking recovery partition (it worked before the letter change), and a useless system volume that doesn't work.

I tried to change the letters and give back the E to the vaio recovery partition hoping that it would work but I can't,I ... Read more

I'm trying to change the letter of the drive, and I followed these official instructions:

BUT, "Assign the following drive letter:" is unselectable/uncheckable. How can I change the drive letter if I can't do this? Thanks.


I need to change it because Flash won't install because my drive isn't C. This is according to the Adobe website.

A:Can't change the drive's letter

You can't change the drive letter of a system partition. More importantly you DON'T want to change it. Here's why: everything, all your settings in the registry (like where it says to load drivers, programs, and everything) refers to drive J: ATM. If you were somehow successful in changing the drive letter, you'd probably get a BSOD at startup because it's failing to find critical files to load.
The only solution (and it's really more trouble than the problem) is to reinstall the OS from scratch on a C: drive (first primary partition on first internal hard drive).

I have Windows installed on my SSD and have some installed some programs on my other drive which is partitioned. I have already removed the drive letter (D) from the system reserved 100mb partition on the other hard drive (it used to have windows installed on it).

So now my partitions/drive letters read C, E, F, G but I want them to be C, D, E, F.

The programs are installed on on F which I want to rename E, will the appropriate registry changes be made if I change the drive letters using Disk Management?

IT does say "change drive letter and path" so I am thinking it will work but just want to be sure. Thanks.

in 7 you can just get rid of the drive letters. name each drive for what they contain, then go to folder options in control panel and uncheck show drive letters. easier than trying to be sure that all paths updated.

After a Reboot, while using Easeus Partition Master, my D drive disappeared. I assigned the D letter to it in Disk Management and when I rebooted again, the D letter was taken. I was forced to assign letter Z until I figure out what to do.

The device D letter is assigned to now, does not exist in either Registry of Disk manager (check screenshots)

The only place where I can see the culprit occupying D is in My Computer. I checked Deamon Tools or similar programs and neither of them uses such a drive. Can you please help me sorting this one out? I can't switch back to D: with any of the three possible methods (Disk Management, Regedit or diskpart command in CMD). This letter simply deosn't exist for the computer.

P.S.: I have 2 more partitions but the are containing Linux and they are not touched for quite a while. It can't be them.

A:Drive Letter is Already Taken, but I Can't See it or Change It

Below is my section of the Registry, I show the A: floppy drive but there is no A: drive in the computer although it can be enabled in the BIOS. Most newer BIOSes don't list the A: and B: options although Windows reserves those 2 drive letters for floppy drives. A USB floppy drive will show differently, take an available letter.

Z: is usually assigned to the first Networked drive such as a NAS/Network Attached Storage drive, mine is although it's not showing on the list.

I do have several drives listed but not all show in Disk Management or Windows Explorer as they are memory card slots/card reader in the computer and won't show until a card is inserted and some are External USB drives.

Hi, so I've done a whoopsie. I had windows 7 on a SSD drive, assigned C: by windows 7, but it was full so I decided I'd clone it onto a bigger SSD drive using Acronis Disk Director. Went swimmingly I thought, both drives contained the same data. I wasn't too sure what my next step ought to be, whether acronis will have sorted it so that my new SSD now has the orginal SSD's drive letter or not. If it did, it will be mean a simple transition. But you guessed it, it left the drive letters the same, so when I booted up, it loaded from the orginal SSD. I then changed the original SSD drive letter, and used EasyBCD to remove the original boot and create a new one with the new SSD.
Unfortunate now when I boot up Windows 7 I get a Preparing Your Desktop message for a couple of mins, but it's then followed by a screen with a cursor but no desktop icons or taskbar. It also seemed unresponsive to keyboard strokes. Any ideas?

I just had to do a fresh install of my win7 ultimate and as always windows changes the drive letters. without going into a lot of stuff you don't want to know my problem is.

I have a redundant backup system on my drives for example I had drive L: F Drive and that had a copy of my F drive and I had a O:f Drive with a second copy. OK I'm

Now that my drives are all different letters on this new install of windows I have a problem.

Can I do this, I know I can change the letter to whatever I want but if I change F drive to S will F be available to me to use. My F drive is now E and want to change all the letters to letters that I didn't have and then change them again to the letters I did have to keep my backup correct. I am wondering if I change a letter is the old letter available to me to use again.

Thanks hope this isn't so confusing

Hi people,

I need to install win3.1 to run an old application. I have tried using DosBox and running 3.1 within that but it is waaay too slow I need w3.1 to be installed clean on it's own drive C: then install the old app for a dual boot system with XP.

I currently have XP-home installed on C:

Is there any way I can change that XP drive assignment to D: and create a new partition to use as C: for the win3.1 install? Win3.1 will only install to a drive C: as will the old app.

I checked the following link but am not sure that it will do what I want to effectively move XP to drive D:

A friend is running Windows 8.1. Her external USB hard drive used to be assigned the letter "E". She says that for an unknown reason, that USB hard drive is now assigned the letter "J" but she would like to have it back to the letter "E".

I opened Disk Management and tried to change the drive letter from J to E. When I click the drop down arrowhead, the letter "E" is available so I select it and click OK. Win8.1 then says the drive letter E is mapped to a network or local drive.

When I look at all of the drive letters in Disk Management, the letter "E" is not assigned to anything. Plus the fact that the letter "E" is in the drop down list of available drive letters.

Anyone know why this is happening and how to solve the problem?

i need to have a drive D:\ that i can use foe symlinks etc. so i created a 20MB partition on my SSD drive. The drive must get the drive letter D:\ because of path reasons for production stuff.
Now when i use the Win 7 Drive Manager, there exists a CD-ROM drive that hijacks the D: drive letter.
I went to the boot menu and deactivated the DVD/CD drive, but it seems that the DVD/CD drive has 2 recognition components, one as DVD and one as CD-ROM. But it doesn't show in the boot-manager.

Actually now i have even removed the drive from the laptop, but the CD-ROM seems to be reserved in a way under Win7.

Any tips around on how to get drive letter D:\ booked on my SSD partition ?


A:Change Drive Letter of non existent CD-Rom

Re-enable the DVD drive
Change it's drive letter in Disk Manager to U or any other letter than D

If you ever reinstall or use a restore point prior to making the change, you'll have to change the DVD drive letter again.

Any device you plug in will take the lowest letter available, so if you plug in a thumbdrive, you'll have to assign that a higher letter too.

It might be better to change your production scheme to use a higher letter (P for example). I don't know the details of your production, so while it might be better, it might not be easier.

Why U? It's geek - the file system on optical drives are UDF. Put a normal disc (not one you burned) in your DVD drive and look in Disk Manager.

I recently had to wipe the hard drive of a new computer (Intel mobo, core duo E8400, 500GB Seagate drive) clean because it had developed some problems (like having to reboot after coming out of standby or hibernate), and no system restores or Windows XP repairs did anything. I use a program suggested by J & N computer support, where the custom computer was build. It's called "AEF", which you run from a CD. It destroys the partition on the HD. However, the only option I could find when I ran it was "delall", which deletes all partitions. When I installed Windows, it assigned drive letters to the card readers FIRST, and the HD last. So now my HD is H: and my CD/DVD writer is G: IOW, it assigned the letters in reverse order.

Diskmgmt.msc will not allow you to change the boot drive letter. I would rather not have to destroy the partitions again to get it to make the boot drive C: (how do I do that, anyway when the Windows install disk seems to have a mind of its own?). Is there any commercial software on the market that will allow you to change the boot drive letter?

Hi, I recently bought a new PC:

Intel i7 Processor 870 (2.93GHz)

ati 4350 video card
350watt (400watts peak) Delta PSU
Windows 7 64bit Home Edition.
! want to partition the 1.5tb HDD into five partitions:
C, D, E, F, G.
I shrunk the HDD the maximum allowed, 718MB, (need to move unmovable file before I can shrink it more), started to create another drive in Disk Manager
but the new Drive was assigned drive Letter "J" I want to keep the HDD drive assignments sequential C,D,E,F,G. (I'm going to change the DVD drive letter from "D" to "X") .

Win 7 Home Premium 64bit Device Manager Disk Drives show five Drives:
generic USB CF reader USB Device
generic USB MS reader USB Device
generic USB SD reader USB Devic
generic USB xD/SM reader USB Device

can I change the drive assignment for these devices so i can make the new HDD partition drive letter assignments sequential?

How can I move unmovable files on "C" partition so i can make it smaller?


A:need to Change Drive letter Assignments

The easiest way would be to disable the various readers and then change the HDD around. This will allow you to use successive letters for the drive and then reallocte the letters for the other devices.

Generally the inmoveable file is the swap (Page) file. You can turn the off in order to shrink the drive and then turn it back on when finished. When it is turned back on it will place itself in a different location on the C: drive.

Hello everyone,

Recently, for no apparent reason, Windows decided to change the drive letter from F to L on one of my drives. Before I discovered how to change it back again I made the error of manually trying to rename it which caused it to add the letter I wanted preceded by the letter "L" it had applied. Now I cannot get rid of it.

Can anyone tell me how to solve this so that the drive label is F: only please?

Right-click the drive or device you want to change, and then click Change Drive Letter and Paths.

Hi -

I thought that I posted this question this morning, but in looking through today's questions I don't see my post. Maybe it was moved? Anyway, here it is: 5 yr old Sony VAIO desktop with XP Pro. The floppy a: drive broke and I physically removed it. I bought an external drive (USB) which became b: (obviously before I moved the a: ). I know all the floppy jokes but I'm old and I still use them. I also come across situations when they are called for (I can't make Microsoft's boot disks, etc.). Neither a: nor b: show up in Disk Management so I can't change the letters that way. I've actually tried to remove all the places the a: (phantom) driver shows up. I've hit "uninstall" in the device manager but that only works until I turn the computer off and back on. The computer says that it "found new hardware." I've exhausted my knowledge here. Some programs tell me to insert a floppy disk and when I put it in the b: drive it isn't recognized. I never go in the registry because, frankly, it scares me I've been in the BIOS for very minor things. Can anyone please help me to get this floppy drive to become my a: drive (or maybe just get rid of every trace whatsoever of a: since I deleted the driver everywhere)? I could get the a: driver back if I need to. I was stupid and not thinking about maybe needing the driver. I figured the b:driver will come with me when I call it a:

I have Win 7 running from C: drive and another Win 7 from D: drive (pro versions with different languages).

I have to change the boot drive in the BIOS of the motherboard, each time I want to switch the OS (rarely).

I bought an SSD recently, switched to the D: boot, connected it over USB and used the supplied Samsung disk mirroring utility to move the system to the 840 PRO automatically (it's obviously used D: as the current system drive).

Then, I have removed all of the old drives (C: and D: ) and installed the SSD in place of C: drive.

The system booted fine, except for the "temporary user profile" warning. The SSD have the C: letter.

Using regedit, I have fixed the "temporary user" issue (renaming the .bak profile entry and correcting the user path inside).

Then, using the regedt33 app, I have replaced all of the "D:/"s to "C:/"s in the registry and rebooted.

The system seem to work fine on the surface (surely, except for some shortcuts).

My question is: what else should I check, to make sure the system is in perfect shape now? One of the ideas - search for any "D:/"s in the files on the disk (configs). Does anybody know of any Windows 7 config files, I have to take care for explicitly? Another idea is to run some system integrity checking app - could you recommend any?

Just please, don't use the "clean install" words in your answer, I'm fed up with that Google search result already.

I have a non-serious, but puzzling situation. I have an external USB Iomega hard drive. I have it set to be Drive Y. It works just fine. But every once in a while, its drive letter changes. The first time this happened, I thought that the drive wasn't working, because I tried to copy something to drive Y, and found I had no drive Y, even though the power light on the drive was lit, and the drive appeared to be functioning. The only tell tale hint I had was that right after Windows finished booting, I got what I'll call an "error beep"--the sound that Windows makes when you try to do something you aren't allowed to do. Rebooting did not, however, bring the Y drive back. However, what DID happen was that after Windows had booted, I got a dialog box that asked me what I wanted to do with the Iomega drive J--the kind of box you get when you insert media into a removable media drive. That gave me the clue that the drive was working, it had just been assigned a different drive letter (J was the first unassigned drive letter on my system). I went to Disk Management, changed the drive letter back to Y, and all was well.

Since then, this has happened about 3 or 4 more times. Each time, I can use the Disk Management feature to reset the drive letter, and it is then fine for several days or weeks. Does anyone have a clue what could be causing this behavior?

You can do that in Disk Management. Right click on the drive(s) and you will see. But you will first have to assign a different letter (e.g. M) to E or D to free up that letter. If you have data on E, it may lose the path though.

A:Change Drive letter: Partition containing OS

I have never been able to change an OS to another letter without bricking the OS. The only tutorials for doing so make it clear it is only if the OS letter has slipped.

What I would do is save externally a backup image of Win7 using an imaging software that will allow you to select where to reimage, such as Paragon Backup & Recovery Free Edition - Free Download or Macrium Reflect.

Then go ahead and do the Vista factory restore, shrink Vista partition in Disk Management, reimage Win7 to the shrunken space. Now boot the Win7 DVD Repair console to run Startup Repair up to 3 separate times to rewrite the MBR to Win7 and possibly configure the dual boot. If not, use EasyBCD 2.0 beta in Win7 to add VIsta.

Others may have an easier idea. You'll have the backup image as a path back, so it's worth a try since Win7's drive letter is in most cases relative anyway.

Dual Boot Win7 x64 beta
XP x32

After installing Win7 into a new partition, the OS started up fine from the new dual boot screen, but I didn't have access to my Win XP partition from within explorer. In disk management, I was able to add a letter to my WinXP volume (I took the next available "O") and it popped up in explorer no problem. However, after restarting, Win 7 begins to load, then BSODs way too fast to think about catching with camera. I got the option to run startup repair at the restart, and I did so. The conclusion there was that I had plugged in a device during the last session that was now causing problems. That is bogus, unless that device is my newly lettered partition. I read many a thread in here about re-lettering a partition that had lost its letter in the intall (usually the other OS volume in a dual-boot environment), but didn't see those posters then have issues upon restart.

I can boot into XP, although here now NONE of my drives have letters.

Sounds like you didn't "clone" the drive, but merely copied the files which won't work. You need to use a utility like DriveImage XML to copy your data to a new drive. Also you need to make sure that the new drive is the only drive in the computer when you attempt to boot since that's the one that normally gets labeled as C: drive.

The problem is that when you installed the old drive
had already been allocated drive C.
Windows will not allow you to change the system drive.
In order to get around it,you will need to reinstall
with the slave drive disconnected.
Since you have changed the original drive,
you may not have to disconnect it but a
reinstall is needed to make your system drive C.

I installed Windows 8 on the SSD and put all my files and the majority of my programs on the HDD. The problem is that the HDD was originally partitioned into two, and I would install all my programs onto the second partition, since that was my data one. Windows 8 assigned C as the drive letter for the SSD, D for the first partition and E for the second partition. My problem is, though, I got rid of the D Drive because it was a hosed Windows 7 install that I was keeping just in case I forgot to backup something, but now no longer need. It annoys me now to have a C Drive and a E Drive--I would like to rename the E drive to a D. However, since all my programs are on the drive, I don't want to break all of the start menu links and the like. Is there a way to do this without any pain?

I seem to have a problem with my external USB drive.

I needed to change the letter of one partition from H: to E: and it wasn't a problem.

To my doom, I had a usb dongle plugged in that had the E: letter assigned to it. The drive letter changed but left the partition unreadable (winXP wants to format it and Ubuntu says that the partition is not NTFS anymore).

Any ideas please?

I installed Windows Server 2008 R2 onto a computer that was running Windows 7. I installed it onto the secondary partition, D:\. I assumed Windows would automatically switch the drive letters around to make the System Drive C:\. It didn't.

How can I change the system drive letter without breaking everything and without a complete reinstall? I've tried the obvious method of 'just' changing the drive letter but that ended with the PC not being able to boot at all.

If some one can enlighten me I would really appreciate it.

Thanks in advance .

Hey there,

I have a serious problem with my poor computer and I'm relatively sure it's entirely my fault.

I'm running WinXP Pro. Yesterday I invested in a new 500GB Seagate SATA HDD. I installed it fine... that was okay. It was running as drive E:. I initialised it and set it as a basic partition, then formatted it as NTFS. That's all okay.

Then I used a program (DriveImage XML) to copy the entire partition from my 30GB IDE C: drive onto the 500GB E:.

This also worked fine. I even went into the BIOS and changed the boot order, and got it successfully booting from E:. Okay, that's cool. I went into the registry and following the instructions in the windows support area on the microsoft website, I switched the registry entries for C: and E:. E: is now the System Disk. I fix the page file to be on E:. That works okay.

Right. Now the next task is to make the 500GB Drive into C: instead of E:. Problem is, the original 30GB IDE is still set as C:.

Okay, I think. I'll just go into Administrative Tools>Computer Management>Drive Management and switch the 30GB drive from C: to X:, thus freeing up (the drive letter) C:. I'll switch the system disk to X:, change the 500GB drive (E:) to be the new C:, switch it back to being the system disk and then set X: to E:.

This would, theoretically, make the 500GB drive into my C: drive, and the old 30GB into E:.

So I set out to do this. I changed C: to X: and it asked me to restart for this to take affect and free up ... Read more

A:[SOLVED] Help!! Crash After Drive Letter Change

Hello Silentwolf, Welcome to TSF!

Don't Panic...this is easily resolved...

Turn the computer OFF...disconnect that smaller HDD which is now X: or can physically leave it in the computer if you intend to use it again (we'll guide you into setting that up), or for this task, just disconnect the IDE ribbon and the molenex (white) power plug; set the 500Gb HDD as "master".
Reboot the computer...this time your 500Gb HDD will be automatically recognised as the C: Drive and boot in to Windows?.

Once thats done, and if you still need the 30Gb HDD, turn the computer off again and set the 30GB HDD as 'Slave' and plug it back in; reboot the computer.
You should now have access to the 30Gb HDD, so that you can change the Drive Letter to one closer to the C:.

Becareful that you do not attempt to boot from this 30Gb HDD or enter any of the Windows System Files that are on it, as this will cause major can now also delete all the data on the 30 GB HDD and reformat it in NTFS format.

Give this a try and post back with the result.

Kind Regards,

I have an HP dv9500 laptop that was giving me some problems, so I bought two external HDD enclosures so that I could take out the hard drives and transfer the data to my new laptop. To avoid confusion with other external drives that I've attached, I renamed the two hard drives H: and P: on the new laptop.

After I transferred the data, I put the HDDs back into the original dv9500 and was going to run the restore disk. However, now it won't even power on, as if the motherboard has gone out. I had the motherboard replaced last August, so I really hope that's not the problem now!

I'm wondering, since I renamed the C: drive that hosts the OS on the new laptop, will it change the letter in the original laptop as well, causing it not to find C: in order to boot? Just trying to rule some things out before I write it off as a piece of junk. Any help would be appreciated!

A:Will changing drive letter of HDD on one computer cause it to change on another?

A drive letter assigned on one computer has no effect on a different computer. However, if you modified the system drive letter (C in Windows while it was booted up, you'll have all kinds of problems, and I doubt the computer will even boot up again.

Erm, this is marked solved with no responses.

Changing the drive letter is a bad idea. Having something other than C:\ as the boot drive is very inconvenient, but the risk IMO is too high. Many applications do not work after the drive letter change process.

I have built a computer for video editing and named the hard drives (C for the main drive, (M for the drive holding my music, (P for the drive for photos, and I named the drive to store my videos (V. However when I tried to write path to the V: drive I was told V: is an invalid path, I suppose because of the confusion with a \ followed by a / which would give you a \/ which can be confused with V but is not exactly the same. I went to My Computer and right clicked on the V: drive and clicked on "rename" in the drop down menu and changed the name to "Storage" but the (V persisted. Then I renamed again and named the drive "Storage (S" and now in "My Computer" the drive is shown as "Storage (S (V" When writing a path to put videos on this drive can I use either S:/ or V:/ to get videos into this drive? Is there some way to remove the (V ? Thanks.

A:How do I change letter designating hard drive (V:) ?

My guess is that V: might be in conflict with one of your removable media drives. On my new DELL with a multimedia card, I have a V: which is associated with a SD/mini-mmc/rs drive. There are also drive letters S:, U:, and Z: defined for various things (Z: is my CD/DVD drive).

The way that I found to remane drives and drive letter assignments is a disk management tool. Go to the Start menu, right click on Computer and click on manage. That opens up a menu to a lot of things. The thing you want is near the bottom called disk management.

Once you have the disk management screen displayed, you can right click on any drive volume to get a menu of things to do including change drive letter.

After replacing my laptop hard drive with a SSD, I decided to install that hard drive into my desktop computer to get the data off it, and eventually use it to expand the storage on my desktop. However there is a conflict of drive letters, as both drives identify themselves as C.

I can get it to work by unplugging one drive, then plugging it back in after windows has booted (that drive is assigned the letter D by windows then) but this is a tedious solution. Is there any software available that will enable to to change the drive letter of either drive?

I installed XP on drive Z but XP thinks it's on drive D. Drive D is what my vista recovery stuff is on (I dual boot)

A:Is it normal for XP to change the drive letter, but it's not actually changed...

A boot drive (drive with bootable operating system) will normally be assigned the letter C: in Windows, even if it is a multiboot system.

Of course, this can be changed by drives attached on an install using a MS OEM version of XP or various other things which were not necessarily done in the proper sequence. I've seen this on my system but I cannot recall the exact circumstances.

As for the Z: letter change...I don't believe that XP will assign such to a bootable drive, unless there are 25 other drive letters assigned permanently ahead of it...just speculation, never tried it.

If you installed XP after installing Vista...and with the Vista drive connected during the XP install...then that might account for the D: letter assignment.

I have an external USB floppy drive that got assigned the drive letter B when it was plugged into one of the usb ports on the back of my PC.

I need to change it to letter A. The drive is not listed under computer management: disk management. Removing the drive and reinstalling does not chhange the drive letter. Removing the driver in device manager
results in installing new hardware, but with drive letter B. The Bios has several settings releated to usb devices--but nothing to do with drive letters.

so I am at a loss of how to fix this---any help would be most apreciated

This happens (accidentally) sometimes when loading an XP computer. If you happen to have a zip drive or memory card reader plugged in, then during setup XP automatically makes the primary hard drive, a letter AFTER those!

So in other words, if they have a zip drive and a couple CD-ROMs, XP loads up as drive E: or some such. I've got a PC now with a memory card reader and the main drive loaded as drive I:!
I really dislike that. XP should always use C: for the hard drive. But anyway, without having to reload the whole dang PC over again and unplug those devices, can I just use a program to change the drive letter and make all needed changes? Or is it better to reload to get my letter to be C:?

I know Partition Magic has a drive letter changing utility that you can use when you merge partitions and such. But I'm not sure if any utility can change the system partition drive letter.
I really don't feel like reloading this monster of a machine again.


P.S. And free is always good, if such a utility exists

Failing all of the above, would the fixboot, bootcfg, or fixmbr commands from the recovery console allow you to fix it?

Had an XP dual boot with Win7 RTM. Deleted XP C: drive and moved RTM D: drive over into it's space. I would like to keep and license this installation using retail Win7 Ultimate Signature Edition received with party pack.

Is there a way to change the Win7 D: drive to C: by running a repair install (upgrade over OS) as I would like to find a way to do this without having to do a clean install.

A:Change drive letter using Repair install?

It looks like from some of your other recent posts that you may already have found the answer to this problem. If not, I had (I think) a similar issue in that I actually tried the RC to RTM "upgrade trick" on a dual boot machine with XP, and after it was finished I deleted my XP partition and moved the Win7 partition into the XP space and enlarged it, thinking that when I get my key I will just activate it and be done. When I tried to re-boot, it re-booted properly into the Win7 logon screen but once logged in there was no desktop, no icons, no nothing. After six long hours, I found the answer here:

Multibooters, Vista Dual and Multibooting - Drive Letter Problems

I think this is what you are talking about? If so, the registry edit described here worked for me, but I had to go into safe mode to do it (I could not do the repair with the Win7 disc as you suggested). It took me about 10 seconds to remove the incorrect C: drive letter reference and change the Win7 partition to the correct C: drive letter reference, then re-boot and everthing was fine.

Hope this helps.
