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

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

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.

Help.

Hi PAMDILL,

Welcome aboard.

Try this:

Download drivecleanup.zip 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"

I turned the computer on today and one of the external hard drives has changed from 'K' to 'L'. Two other external hard drives have not been affected. For some reason the 'K' drive has been allocated to the CD Drive (which was previously 'F').

So how can I get 'K' back to the external hard drive using the same path as before. It doesn't matter what the CD drive is called but getting it back to 'F' would be nice.

Thank you.

I have two WD My Passport 2TB external drives operating via USB 2.0 ports on my Qosmio Laptop.

I have no problem changing the different drive letters individually. Lets say the black one is allocated Drive F. When I disconnect the black one, and connect the silver one, it thinks it is Drive F too, so I rename it to G, then disconnect it and reconnect the black one only to find it is now G as well.

When I connect both to the laptop, the first one connects as say Drive F but when I connect the second one as well, it seems to think its F also but the Drive letter cannot be changed while both are connected. I also can only read the first drive, and the second one has no drive letter assigned to it.

The silver one is formatted to Fat32 and the Black one if formatted to NTFS although I don't believe that matters.

What I would like to do is copy all the files from silver to black, then format the silver one to NTFS.

Any suggestions?

Hello.
Recently bought a new Laptop, and went through all the setting up process, one of which was Windows 7 back up. At the time I just went for the partitioned drive option, but after a week, I've decided to buy an external Hard drive for my back ups instead.
My questions are:
1. Can I easily change the destination of the back up files?
2. Do I just delete everything on Drive D once I'm backing up to an external Hard Drive, or will Windows give me this option when I change to external Hard Drive?
3. The Back up is done on a schedule, so how do I get on when the date passes? Will it ask me to plug my external Hard Drive in the next time I boot up?
4. Finally, I'd like to back up our Desktop too, running on Vista. Can I just partition the external Hard Drive, and keep our laptop, and Desktop backed up on the same hard drive??

Cheers, Matthew

A:Change back up files from D Partitioned Drive to External Hard Drive?

Hi Matthew -

You don't need to partition the HD to keep your different backups on it.

The WindowsImageBackup file needs to be named only that and in the root of the external to reimage from the booted DVD or Repair CD, however you can click on it to see which PC it is for.

Backup Complete Computer - Create an Image Backup
Backup User and System Files

I don't like the way Win7 file backup works so I drag the active User folder from each computer here to external once per month, then update the backup image every few months. You may decide to go Manual after trying the automated backup, since you'll need to move the external to catch the backup anyway.

I have a Dell XPS 8700 running Windows 7 professional. I just noticed today that my first DVD drive letter went from D to J. One of my external hard drives used to use the letter J. Now it is D. The DVD drive appears to work OK, but it may be a problem when I do backups using my external hard drives with Acronis. I am not sure when this drive letter change took place. I tried doing a checkpoint restart from a restore point taken 3 days ago. Same problem. Is there some way to get the drive letters back to they way they were? I am used to my two optical disk drives being D & E. Now they are J & E.

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.

A:maxtor external hard drive unformatted and undesignated by drive letter

What size is the hard drive?

Do you know what motherboard you have?

STEP 1: CHECK POWER (click for expanded instructions further down the page)


Verify that the drive light and the light on the AC adapter (power supply) is illuminated normally.
It is sometimes necessary to contact Technical Support for troubleshooting and/or possibly to replace the power supply if it behaves unusually.





STEP 2: CHECK CABLING (click for expanded instructions further down the page)



Confirm that your USB/Firewire cable is firmly connected in a port that is on the rear of your desktop computer (if you have a desktop).
Try another USB or Firewire port.
If your drive is powered only by USB, such as the FreeAgent Go, the Maxtor OneTouch mini, and the Seagate Portable drive, then the drive's cable has two USB connectors. Try connecting both of the free USB connectors into a USB port for maximum power availability.
Avoid connecting the drive via a USB hub for now.



STEP 3: WINDOWS SERVICE PACKS


Follow these instructions to ensure that your installation of Windows XP/2000 has been updated to the latest Windows Service Pack.

Right-click on My Computer and choose Properties.

The System Properties window will appear. On the General tab (which will be at the front), see the "System:" information.

For Windows 2000: Update to Service Pack 4.

For Windows XP: Update to Service Pack 2.

I used to boot into Win8 which has been installed on a partition with drive letter W.
After I ran EaseUS partion manager (Best partition manager software - EaseUS Partition Master Family.), the partition has been enlarged, and at first glance I am able to boot.

Unfortunately, my login screen is not customized anymore (does not display background pictures, apps et cetera), and upon login I can hardly do anything (no desktop is displayed, I cannot start an explorer instance et cetera). Guest logins are automatically kicked out.

Upon logging in (it has remembered by username, and apparently my credentials) it just says 'Preparing Windows' for some time, en then displays a blank screen, in which I can see my mouse, and with ctrl-alt-del get some options, but I'm not able to start the task manager.

When I reboot into safe mode (which is way more hidden than in Win7) I ?m able to start a task manager, en from the I can run items, browse my PC et cetera. However, I can see that my drive letter has been changed from W to E. Most of the application I start are broken, like when I start the MSC snap-in in order to maybe change the drive letter using Windows' built-in partition manager, it state it is broken.
When I try to change the drive letter using the command prompt and 'diskpart', I'm not allowed, as the drive I want to assign a drive letter to is a system drive.

I seem to have suffered no data loss (I've got most stuff backed up anyway) but don't want to re-install either.

I don't have details on what was done to change the drive letter, because I wasn't the one that did this. But here's an overview of the results:

The removable drive shows up in explorer with its new drive letter, however when you click on it, Windows (using Vista and 7) says that it must be formatted before use- checking the drive properties shows a wrong hard drive size.

I'm thinking there are 2 ways of resolving the situation:

1. getting an outside program that will access the drive and allow me to copy the files to a different drive (then formatting the removable drive) or
2.somehow getting Windows to recognize the files on the removable drive.

If anyone knows what software I can use to access and copy the files on the drive or how to get Windows to recognize the drive that it used to recognize normally, I'd appreciate it.

I have an old BYTECC hard drive enclosure. Trying to use it on an older XP system for back up. Got a bunch of 40G hard drives I can use.

The OS will detect the external drive is connected and powered up, arrow shows in the tray for a USB drive, checked the device manager and it sezs the drive is there and operating properly, recognizes it, but does not assign a drive letter.

AIDA32 sezs it is there but same deal shows no drive letter.

I've tried four different hard drives with the same results. I know the hardware works on other computers, this particular computer USB works with other canned external drives, it reads a flash memory stick as a drive no problem. I know the BYTECC is set up properly, should be the same as with other computers. Works ok on a Win2000 system.

What could be the problem? Is there something to tweak?
I do know this XP system would not read hard drives that had been formatted on non-XP computers before. Don't exactly know what systems all these drives were formatted on. Isn't making any sense to me at the moment. Doing it just like I did on the Win2000 system with other drives, everything worked as it should.

Thinking I could try to slap one of the drives in as a slave and try to format it that way, hopefully can get it to be read as a USB drive instead.

Any help greatly appreciated.

Thanks.

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.

http://www.sevenforums.com/tutorials...ndows-7-a.html

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.

Hello,

Some time ago I put in a new hdd and copied the old one to the new one, took out the old one and the new one retained the letter F. If I would save the content of the F drive to an external Hdd, is there then anyway to clear the F drive hdd and re-install from the external and re-letter the F drive to be my C drive?

Hope this makes sense.

Any info appreciated.
 

A:Wanting to change hdd drive letter back to C

Switching drive letters in Windows really isn't recommended, mainly because a lot of system files (mainly the Windows Registry) are hard-coded to look at whatever drive they were installed to (so in your case it would be F).

There's a Microsoft Knowledge Base article on the switching procedure here: http://support.microsoft.com/kb/223188

I personally would recover all of your essential data (documents, photos, music, game saves etc), wipe the disk and start from scratch with a clean installation of Windows, as you could brick the machine if it screws up.

See if you can disable the floppy device in your bios. Even though you don't have a floppy drive internally, the controller is still there so the bios and operating system reserver A: for the drive letter.

I am setting up a new computer running Windows 7 Pro 64-bit. I attached an old 500GB USB 2.0 hard drive. System notification showed the driver was successfully installed. However when I looked for the drive in Windows Explorer, it did not show up under Computer.

However when I right-click on the drive, the option to assign a drive letter is grayed out.

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?

Hi Guys!
I need some help. I purchased an external hard drive per TSG help. Thank you. Everything has been working so far. I leave the Seagate External Hard Drive plugged into my USB port, which identified it as being on the E:/ drive. Anything else will be F: drive. Suddenly, the Seagate External Hard Drive is coming up as the F: drive location

I placed some programs, such as the Wise Disk/Registery Cleaner, onto the external hard drive to free up limited space on the C: drive. The shortcut indicates the E: drive so the computer is preventing the Wise Disk Cleaner from running. I have unpluged the external hard drive and shut the computer off several time. Nothing changes the drive's location.

Any suggestions????
Thank you.
 

A:External Hard drive changed drive location

Hi Siam, you can choose what letter the drive should show up as. To do this, go to:
Start -> Control Panel -> Administrative Tools -> Computer Management and click on Disk Management.
On the right in the bottom pane you will see a list of your drives. Find the external hard drive and right click on it and select Change Drive Letter and Paths... then click on Change and you can select E: from the drop down and click OK.
Hope that solves it...

I have a new computer that runs W7 Prof 64 bit. I noticed when I got it the following.

Drive C (W7 on it and it's the boot drive)
Drive E (second hard drive
Drive D (CDROM drive)
Hard Drives are both 1TB SATA3
What is on the E drive is data I copied there.
I would like to change the E drive to D and the CDROM drive D to E.
This way my hard drives will be C and D and the CDROM will be E.
I have no idea how to do this. Can anyone help me?

A:Change Hard Drive Letter

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.

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:
Thank You
Dawn

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. 
Thanks!

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.

I have a new 120 gig external USB drive (105G free). It installed and seems to work fine except:
My prior system had hard drives C: and D:
cd reader drive E:
DVD/cd RW drive F:
four-way card reader G:, H:, I:, J: (these came and went depending if card reader was left plugged to the PC)
The new external installed correctly as drive K: and I succesfully backed up a zilllion photos.

After shutting down/startup the drive assignments redefine as
C: and E: Hard drives
D: as new external 105 GIG free
F: as CD reader
G: as DVD/CDR
H: as a second identical new external 105 GIG free (duplicates drive D
The four way card reader is unplugged-ran out of USP plugs.

I have two problems:
1. The duplicate external drive assignment is obviously wrong but I cannot make it go away.
2. I cannot make a backup program work correctly since the drive assignment keeps changing.

How can I "lock in" the hard drive and CD assignments so the external drive doesn't jump in the middle of that alphabet. I want the External drive to always be assigned some higher alpha letter so I can use it on different computers.

I have a situation that isn't really a major problem, but is slightly annoying, and somewhat puzzling.

I have an external 1TB Iomega USB hard drive on my system. It is set to be Drive Y. Most of the time, everything is fine. But occasionally, after I boot the system, I'll get the pop up on the screen asking me what I want to do with Drive J. And yes, the "new" Drive J is, indeed, really my Iomega external drive. I can go into Disk Management, and reassign the drive letter back to Y, and everything is fine again.

Sometimes, it keeps the Y drive letter for several months at a time. But other times, the system treats it as a new drive and assigns drive letter J to it--in anywhere from a few days to several months after the previous time.

As I said, it doesn't happen often enough to be a problem, but I'm curious as to what causes it. Anyone have any insights into this little puzzle?

A:Changing External Hard Drive Letter

Look in your registry under HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices. That's where drive letter assignments are stored. Find \DosDevices\Y: on the left side and note the data value on the right. The next time it happens, check the same registry location but find \DosDevices\J: and see if the data value is the same as before. Also see if there's still an entry for \DosDevices\Y:.

I recently purchased a western digital 1.5T My Book Essential to "automatically" backup my PC's internal hard drive and a Passport External drive I have that contains my media files. I installed WD's Smartware software on my PC and learned that it will only backup my hard drive. I also noticed that it (1) seems to consume alot of processor capacity (computer running much slower with it attached); and (2) my computer won't start up when attached. When I called WD about my concerns they indicated that there is 3rd party software available that will allow me to automatically backup both my internal hard drive and the passport and may not require as much processor space (they wouldn't provide specific recommendations). They also sent me instructions on how to adjust my PC so that it won't try to boot up from MY Book (interesteingly enough I 've never had this problem with my passport). I have not yet had a chance to try their recommendations.

Suggestions on a good 3rd party back-up software would be appreciated.

Thanks

I have Toshiba Satellite, in case that matters. I have drive C, D, E of course. I also have 2 external hard drives. G is for movies only. F is for backup. Anyway, yesterday I noticed that the letter F wasn't showing when I clicked on Computer. I went into Disk Management and tried to assign a letter but I saw 3 G letters. One was fine but the other two confused me. I tried to change each one but the letter F was missing. In frustration I deleted that drive. Well, now I can't get it back. What do I do? BTW, I see the two externals in Device Manager and I think I see one in MiniTool Partition but the drive in question is marked as Unallocated.

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.

Hello,

I recently bought a Lacie 1TB external harddrive to store some of the data on my old PC (Win XP, SP2, I cant seem to udate to SP3 because windows update wont work).

The drive is working fine as I've used it on my laptop running Win Vista (64 bit). However, the drive is not being displayed in windows explorer. When I go to My Computer>Manage>Disk Management, I can see the drive there saying it's online, but there's no name attached to it and when I right-click, all the options are grey (otherwise I could of just changed the letter through there).

Using diskpart on command prompt, I still couldn't change the letter. I also found out that there is no volume assigned to this disk.

Can someone please help me?? I'd be forever greatful

I didn't see where you formatted the hard drive. Before you can use any hard drive, external or internal, you have to format it at some point. For hard drives with Windows installed on them, they are usually formatted during Windows setup. For external storage drives, you can format it through Disk Management.

Hi,

My laptop is a Dell Latitude D830 running Windows Vista.

I've bought a Freecom USB 2.0 Hard Drive XS 1TB (Model Code SSYBBA) which came FAT32 preformatted. I wanted to reformat to use NTFS so I plugged it in to my USB port. Opening Windows Explorer, the drive was picked up as G:\ and I could view files on there and copy and remove files so I knew the disk was working OK.

I started reformatting by right-clicking on the drive letter and selecting "Format" from the menu and select NTFS and kept the default settings. After an hour I cancelled the formatting (clicked Cancel) and a message popped up asking me to confirm, so I did.

Since doing this, the drive is now no longer recognised and doesn't get a drive letter assigned. I've tried rebooting, reconnecting and checking in Disk Management and it just doesn't appear (although is powering up when the laptop starts). Also, Device Manager doesn't show it. Screen shot of Disk Management attached.

Can you tell me, how do I get the drive letter back to restart reformatting?

Thanks in advance for your help.

Alex.
