I'm booting off my SSD which is drive C:\ and I have games and programs on an extra hard drive which was origanally drive H:\ but after a restart it switched to I:\ and when I go into Disk Management to change it Drive H:\ isn't there.
I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.
I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.
You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)
What you say makes perfect sense. So, if a restart changed the drive letter to I, then H won't be there. Why not just leave it at I or is there more to this story...
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.
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"
Update: The mysterious other CD Rom drive seems to be MagicJack.
I did some research but the following tech help did NOT work as you can see by the previous post picture that it doesn't not show it up in Disk Management:

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?
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 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?
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.Read other 7 answers
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 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.
That looks like a mac formatted drive, that's why it wont work on your PC. Try installing Paragon HFS+ for Windows.Read other 13 answers

Right-click My Computer, Manage, Disk Management. Right-click the drive you want to change. You just can't change the system drive letter..
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.
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.

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
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.
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.
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

How to change the system/boot drive letter in XP
If you break a mirror volume or for some other reason the drive letter of your system and/or boot drive gets changed so that the drive now has the wrong letter (not the one assigned to it when you installed the OS), you'll find that the Disk Manager won't let you change the letter of those drives. This is to protect you from making changes that render the OS unbootable, and you should make those changes only if the drive let gets changed as described above. To do so, you have to edit the registry. Be sure to back it up first.
Log on with an administrative account.
Click Start | Run and type regedt32.exe to open the registry editor.
Navigate to the following key: HKEY_LOCAL_MACHINE\SYSTEM
In the right pane, click MountedDevices.
On the Security menu, click Permissions and ensure that Administrators have full control.
Close regedt32.exe and run regedit.exe. Navigate back to the same registry key.
Locate the drive letter you want to change (such as \DosDevices\C:), right click it and select Rename.
Rename it to the letter you want it to have (such as \DosDevices\D:).
Close regedit.exe and run regedt32.exe again to change the permissions on the key back to Read Only.
You'll need to restart the computer for the change to take effect. Be very careful about renaming drive letters of system/boot drives.
I have a problem, that sometimes, after installing Win XP (SP-1), I find the OS installed to another drive then C:.
The machines I've had this problem with, had one (new, empty) harddisk, and a CD-ROM burner installed. The harddisk was always more then 100GB in size.
Usualy the CD-burner would get E: and the harddisk would get F:
I haven't been able to find out why C: and D: is not available from boot.
But is there an easy way to change the drive-letter, once it's been assigned?

How do I keep the NEW 256GB installed drive as C:? Is it possible to change the primary drive letter in Windows 7 Disk Management back to C: after a primary SSD drive switch and system image recovery?
Robinsongs, welcome to the windows 7 forum.
If you install the new ssd in your d slot after restoring your image to the SSD, your bios will normally allow you to
select the boot drive. which you can select as the new SSD.
I would remove the old C drive and place the new ssd in the old C slot. Should be ok.
This way when you boot your machine the bios should automatically boot from your new ssd.
If you have restored your old c image to the new ssd properly.
Bios normally allows you to select boot devices.
I deleted my existing OS then created two new partitions on the same drive. Then I installed Vista on one partition and that partition was properly named "c" as ususal. Then I started Win7 setup.exe from a different hard drive and let Win7 install itself into its own partition. When I got to "My Computer" the Win7 partition was labelled as "I" instead of the expected "C" which had never happend before when I did the same thing.
Does anyone know a save way to label the Win 7 drive as "C" while in Win7?
In the search box, type "Computer Management". From iwithin computer management select disk management and you will see the ability to change drive letters. I don't know if this might mess up your ability to boot though.Read other 9 answers

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 have Vista Home Premium with two 320 GB internal hard drives © & (E). I am trying to put Vista on drive E and upgrade to Windows 7 on drive C.
I had successfully cloned the drive C of Vista onto an external hard drive and copied it to drive E (the second internal hard drive). When I copied the cloned copy of Vista to drive E, the system changed the drive letter to L. Everything was working fine and I could boot into either C or L.
In a fit of neatness I guess, I decided that I would like to have the newly labeled drive L designated as drive E again and changed it to drive E in "Disk Management" while I was booted into drive C.
Now I am unable to boot into the second internal drive. I just get a blank screen. I can get "Task Manager" but nothing else, not even the "Start" icon.
I booted back into C and changed the drive back to L, but that didn't work either.
I tried to boot the second internal drive in Safe Mode, but just got a blank screen, without the start icon.
I tried restoring to a previous date, but that wouldn't work and it only restores C anyway.
When I'm booted in drive C, it shows the second internal drive L and shows all the files and programs that should be on drive L.
How do I get the drive restored so I can boot into it?
Thanks to anyone that can help.
I don't know if this helps, but is drive L still marked as an "active" partition in disk management? When you right click the partition the option should be there to do so if it is not marked as such.Read other 1 answers
I have just bought and installed (to the point of completing initialization under Disk Management) a new 1 TB hard drive. Originally, I was planning to use it solely for data storage.
However, I am thinking of installing Windows XP Pro and all the programs I currently use on it, thereby making it the new OS and programs drive, while using the original 120 GB HD as a data/backup drive.
I think the main appeal of doing this, for me, is that it also presents an opportunity to reinstall Windows on a machine which hasn't had this done for more than three years, and which currently seems to take at least five minutes to boot to a "usable" state, despite having a reasonably high spec for its age (it was bought in 2001, but as a result of the upgrade I did in 2006 which led to the last Windows install, it has a 2.4 GHz AMD chip, an Asus A8N-E motherboard, 3 GB of DDR2 RAM, 7600-series PCI-E graphics card).
This has put me in a quandary with regard to whether I should use the new HD as the OS drive, and if I do whether I should partition it and, if I do that, which drive letter(s) I should assign to it.
I don't appear to be able to choose 'C' as the new drive letter under the New Volume Wizard (I can't even choose 'F' since I have an 250 GB external USB backup drive currently assigned as the F: drive). If I choose 'G' (the earliest letter of the alphabet currently available), must it remain hereafter the G: drive, even if I do... Read more

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.

On the disk right click choices all you have is "Convert to dynamic disk" and nothing else.

You can change the drive letter of anything except the system partition.

I recently installed a new WD 160Gb drive. I partitioned, formated (NTFS) and installed Windows XP SP3 (using the Windows XP setup program). However, the system has reversed my CD drive and the HD letters.
It gave the HD "E" and the CD drive "C". (It should be the other way around) I can not change the HD letter back to "C". It says I can't change the boot volume letter assignment.
I set the boot sequence in the bios to boot from the CD first, the way it should be for installing a OS, right?
What did I do wrong? Why did it assign my CD drive "C" and my HD to "E"?

The blue screen went by so fast I couldn't read it. Soooo, I reinstalled Windows XP Pro and SP3. After doing so, my second HD is not being assigned a drive letter. Device Manager sees it, Disk Manager sees it and says it's healthy, active and NTFS. Is there anything in the Registry I can change to make it accessible?

My problem is that before the drive vanished, it was G:. Now it's D: (first open drive letter.) When I go into drive management and try to change the drive letter, it's not there. None of the drives showing have it, but it's not in the list.
I need this drive to be G: - how do I find where Windows thinks that letter is allocated and release it?Philo Janus, MCP Author: Pro InfoPath 2007 Pro PerformancePoint 2007 Pro SQL Server Analysis Services 2008 Building Integrated Business Intelligence Solutions with SQL Server 2008 R2 & Office 2010 Blog @ http://philo.typepad.com/with-all-due-respect/
The problem was that the drive letter I needed wasn't in the list.
A note for anyone who reads this in the future who does support - when working with someone who says "a drive letter is missing" make sure to understand if they mean the drive doesn't have a letter assigned, or if the problem is that the letter they need
isn't available. I saw a LOT of this while I was researching this problem - I could tell that the person asking the question was saying that the letter wasn't in the list, but the person trying to help would just point them towards drive management (where
they already were, if you read carefully)
In my case, it turned out I have software running that mounts iso files as CD drives. That's where the drive letter was - it had taken the assignment, but without an iso mounted, it didn't show up in drive management.

My primary HDD was failing so I backed it up and replaced it with a larger 1TB drive. After reinstalling everything the new drive is displaying the same size as my old drive and the extra space available is unallocated. I can allocate it as
a separate drive but I find that annoying and would prefer to just have my primary C: drive show up with all of the available space. I formatted the extra space and made it available separately as drive G hoping that I could EXPAND drive C but that option
is not highlighted as selectable on drive C for some reason. Should I just live with this extra space or is there a way to easily combine C and the new G space?
Ok I've changed my one media HDD from letter D: to letter M: & now want to change it back to letter D: since all of my files/directories are set to the D: letter.
But now Diskmanagement is giving me just about every other letter other than D: to change it to.
And when I try to change it to another letter, it gives me an error saying:
The Parameter is incorrect
Does anyone know what this error is & how I can force it to rename my media HDD letter to D: so all my directories fall back into place?
You might see if you may be able to change the drive letter using OPTION TWO in the tutorial below.
Hope this helps,
My brother bought a new internal 500GB hard drive a few months ago and saved all of our family photos to it. Well a few days ago he noticed it would not show up as a hard drive in 'My Computer'. If we go to 'Disk Management' the 500GB hard drive shows up without a drive letter and is marked as a Recovery Partition. Does this mean we lost all of our family photos that were on the hard drive?
If you need more information feel free to ask. I'll attach a photo of what i mean.
Welcome to Seven Forums BinaryMadman
The 500GB drive should not be listed as drive 0. shut down the system and swap the motherboard connectors on each drive. Let us know how that effects things for you. Go back to Disk Management, right click the drive in the bottom pane, Assign Drive leter (any will do).
I purchased an external USB2 hard drive case (that has a power cable and USB output cable) and installed a 120GB Seagate drive. It seems like my laptop (running XP, USB1) will recognize the drive when I plug it in (as an USB Mass Storage device) but it does not give it a drive letter (like E) for me to access it. I have tried changing the Master, Slave, Cable Select jumper on the drive with no success. When I plug in a USB thumb drive, my laptop assigns a drive letter and I can access it via Windows Explorer with no problems, but with the 120 GB external drive, I have no luck? The drive shows up under the Control Panel.....Device Manager as a hard drive just under my laptop drive, but there is no way to store files on this external drive. Any suggestions?
Hello and welcome... You may need to configure the drive in winXP for it to be seen properly.
Control Panel---> adminstrative tools---> computer management---> disk management...
Does it see the hard there? I believe it will show up as Disk1... Select it and format it, you can also change the drive letter if you would like
I have a USB hard drive formatted NTFS that my computer recognizes, but will not assign a drive letter. When I go to Disk Management, it shows the partition as "Healthy (Active, Primary Partition)". When I right-click, the "Change Drive Letter"
option is grayed out.
I have several USB hard drives that this computer won't work with.
I have no problem with USB thumb drives, SD cards, etc. Also, some of my USB hard drives do work!
I have Windows 7 Home Premium.
These USB drives work fine on my two other Windows computers (Vista and 7) as well as on my Mac (10.3).
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.
I ran Microsoft's Computer Management application. Under Disk Management, I see that the drive does not have a drive letter (see attached screenshot). However when I right-click on the drive, the option to assign a drive letter is grayed out. I searched Microsoft's documentation, but the only reason I could find for not being able to assign a drive letter would be if the disk was a system partition or boot partition. But this is just an ordinary HDD that I want to use for backups. What am I doing wrong?
Try to reformat it with NTFS if there is nothing on it. Use Partition Wizard free if Disk Management won'tRead other 7 answers
Using Easeus pm pro 6.01, I received an error that drive G error wouldn't allow the
resizing of 100 gig. Drive G was a Daemon Tools pro virtual drive which I unmounted.
Windows disk management would only allow a 50 gig resizing. I get the same error after
unmounting the G drive although at the time I didn't know I was limited to 50 gig. I really don't want to uninstall Daemon Pro as it is a giveawayoftheday program. Is there a workaround
to this problem and or uninstalling Daemon pro most likely the fix for the problem?

Another fine mess Ollie!
Had some recent print problem (wouldn't) and decided to reinstall the printer software driver etc- Have a Lexmark X3350 (Fine machine). However since the first printer install my C drive has gotten fatter and the software says there is not enough space for it to install on "C"(-which it insists is where it has to go?) Even after I uninstalled the printer? No apparent option available to change the "target" drive!
My now designated "E" drive has gigabytes of space but no way,it seems, to install the printer to this drive? I thought of removing the "C" Hdrive (My system OS stuff Win 2K is all on the "E" Hdrive-- but not sure if this drive will become my "C" Hdrive if I remove the wimpy (Original) 196 MB!! and go to the "E" Hdrive (184 GB). Is this feasable or is there a more elegant solution to get the printer installed onto the "E" Hdrive without dicking around with the software (I'm not qualified for that approach, Ollie?) What say? Thank you
move my documents to E right click on icon on desktop/properties/move/ in target type the path to E: make a folder on E:\ documents and move all the files to that folder. clean out temp files get utility here...
defrag C you need at least 30%of C free for xp to operate properly..
install your printer to the default setting..

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.Read other 9 answers
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 anal..lol
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
Yes, the old letter that is released will be available to be assigned to another drive.Read other 9 answers
I'm trying to change the letter of the drive, and I followed these official instructions: http://support.microsoft.com/kb/307844
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.
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 done this before but done forget how, lots of other stuff has traveled the old brain since then maybe i need to defrag my mind, anyway I need to know how to change my drive letter somehow on my partitioned c: d: drive d: is now g: and i would like to make it d: again if possible.
Thanks Mr. Bill
