Disk Letter Change Makes OS Unusable?

Jun 13, 2012

I have an OCZ vertex 3 as my boot drive and a 2TB Hitachi drive as my storage drive. When I installed the system, I changed the 2TB drive letter name to G. Recently, I installed a card reader into my system, which somehow made one of the card slots G and the 2TB D. Now I can't run any of my programs installed on the mechanical drive. I can't even open diskpart

Change Drive Letter For Presumable Needed Boot Disk

Dec 5, 2009

Windows 7, 32 bit, 12 partitions on 3 hdd's, Windows 7 on C:

When migrating to Windows 7 I first tried to update my Vista which I had used happily for 2 years. Installation went fine, but there were too many problems after.

So I bought a new 1 GB hdd and installed Windows 7 there from scratch. It is on a partition with drive letter C. I copied most of my old partitions to the new hdd, went fine.

When trying to delete one of the old hdd's with EASEUS Partition Master Home 4.1.1 manager software, there is one partition on it (which once before was called C, then successfully renamed to Z ) which I can't delete. I has on it the following folders:

$RECYCLE.BIN

Boot

System Volume Information (locked)

-->and files:

BOOTSECT.BAK

bootmgr

They are only 30,5 MB in size. So I resized the partition to 1 GB.

EASEUS characterizes it as Status = System, Pri/Log = Primary. Windows Disc manager characterizes it as System, Active, Primary Partition.

My question is: Can I change the drive letter from Z to B without risking the whole system to be unbootable? (and maybe never be bootable again?) When trying I just get the usual Windows warning.
I would be most grateful for an answer explaning what and why or why not.

Virtual Disk Manager - Cannot Change Drive Letter / Parameter Incorrect

Oct 17, 2012

So I can't change the drive letter. Do I need to use Partition Magic again? The more I keep hearing/reading "do you have a backup?" - makes me believe the tool (OS) isn't capable of handling/accessing the data properly.

Can't Change Hard Drive Letter To Needed Letter

Nov 16, 2009

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?

Change A Drive Letter From Outside The OS?

Aug 20, 2010

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.

Way To Change Drive Letter

Nov 4, 2010

I have a triple boot system:

C - Windows 7 Ultimate - SSD array D - Data - WD 640 spinner 1 E - Windows 7 Pro - 1st partition on WD 640 spinner 2 F - Windows 7 Enterprise - 2nd partition WD 640 spinner 2

Using Acronis True Image 2010, I keep 2 images of each OS on D.I'd like to put an image of C onto E, then make some changes to it. I think I tried this back in the Vista beta days, but can't recall if I ever got it to work, tempted to say "no".

X64 - Drive Letter Change - BSOD

Jan 17, 2009

Dual Boot Windows 7 x64 beta

XP x32

After installing Windows 7 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 install (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.

Any Help? I really was diggin' my Windows 7 time, and really enjoyed taking advantage of all my RAM and x64 versions of CS4 and CAD.

System Partition Letter Change

Jun 2, 2009

The system:

Drive 1: vista boot loader, vista32, two partitions (vista on C, some stuff on D), both NTFS

drive 2: broken grub loader (never mind actually), one ntfs partition with some porn, games, and other usual stuff . named E.

so then, i copy the 7100 x64 distr into my flash drive, boot it, and install our beloved 7even into the drive 2. it does not ask me anything, write its boot loader to drive 1, lets me choose which OS to boot into each time... perfect. BUT(T):

7even named her own partition C, while drive 1 partitions became D and E. i swapped last two easily, using 7even's disk management utility. that's 1 of 3 and that's not enough. i really want 7even's partition to have the same letter as in vista. i even googled it, and didn't find any answers.

7even is still unconfigured, so it would not be a problem to reinstall it. even more, if it's really necesarry, i can move all of drive 1's data somewhere else, so i can format it.

Change Letter Designating Hard Drive (V:)?

Dec 28, 2012

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

Cannot Assign Drive Letter In Windows 7 Disk Manager

Jun 14, 2012

I was asked by a client to get data off a circa 2004 PC that has a blown Power Supply. I removed the HDD and proceeded with my usual recovery procedure using a drive adapter cable and power supply. The problem is that I can see the drive in the Win7 Disk Manager, but I can't mount the partition. Most of the time I've not had problems with Win7. It usually just recognizes the drive and assigns a letter to the active primary partition. In this case, I can see the partition, it's active and healthy, but I can't assign it a letter. In fact, all options are "greyed out" except "Delete Partition."I've also used MiniTool Partition Wizard, but without success. Partition Wizard can assign a letter to the partition, which then shows up in Windows Explorer. If you click on the drive letter, you get the "J:\ refers to a location that is unavailable ...." I can explore the partition with Partition Wizard, but I'm unable to access the files.

Here are the Hardware particulars:Old HDD: 80GB Maxtor HDD ATA, formatted with 76GB primary partition, Active, NTFS, This was the boot drive for a PC I'm using Win7 x64. The drive is connected to my machine using a SATA/IDE Combo Drive adapter connected to a USB port on my machine. It uses the standard USB to SATA Serial Bridge Driver.

'Path Does Not Exist' Error Constantly After Drive Letter Change?

Nov 4, 2012

Ok so here's a little backstory before I jump into my problem. I've got 2 harddrives installed; a SSD and a regular HDD. The SSD is labeled C: since it has Windows and other core programs while the HDD is labeled B:. The solid state is almost full while the regular one still has over a terabyte of space left to fill up. Normally, I have no problem installing new programs or games to the HDD till now.When I went to install my new game on B: it kept giving me invalid directory errors. So I went to the game's forums and discovered that the reason that issue was happening was because the game recognized drive letters A and B as floppy drives as opposed to hard drive letters. Further investigation revealed that apparently this little bit of design is hardcoded into the game and there really isn't any work around except changing the drive letter. So I looked up how to do so and made the change.....then the problems started.After changing the drive letter from B: to Z: I kept getting 'path does not exist' error message with features and hardware connected to Windows on C:.

For example, my DVD-ROM drive is labeled D: and everytime I tried to install the game after the drive letter change I got 'D:\, path does not exist. make sure the path is correct and try again' error. Another example, when trying to go to Device Manager to start a fix I couldn't because of 'explorer.exe, path does not exist' error. Basically, every step I tried where anything was connected to C: or D: I got the 'path does not exist' error. At this point I've done a system restore to before the drive letter changed and I'm running as I was before trying to install the game.My question is, how do I change the driver letter of my HDD without getting all the 'path does not exist' errors? If that's not possible, how do I fix the 'path does not exist errors' when the path starts with C: or D:? Is it done the same way I would with a program through the properties tab in the target path section and start in section? Or is there something more invasive I need to do when the path issue starts with C: and D:

Change Drive Letter For Upgraded HDD On SSD-OS/HDD-User Files Setup?

Nov 3, 2011

I recently set up a new Systemax SYX-1113 PC with a SSD (C:) for Win 7 Pro and a 1TB HDD (G:) for my user libraries and programs. I need to upgrade the HDD from a 1GB to a 2 GB drive so I cloned the 1TB (G:) drive to a new 2TB (H:) drive. My new challenge is figuring out how to switch the drive letters on the two HDDs so that Windows looks to the new drive for the user directories and program files. I tried using disk manager in Windows 7 and got the BSOD - I guess it didn't like me changing the location of the active user profile. I assume I need to boot the PC from something other than the C: drive to make the change.

External HDD Not Appearing In Disk Management - Drive Letter Not Assigned

May 11, 2012

I have an external HDD that works on any other machine I test it on, except mine. It was working and for some reason I recently needed to use it and it didn't work. It appears in device manager but not in disk management. A drive letter might not be assigned to it, I can't see it in disk management to assign a drive letter to it.

External Hard Drive - Drive Letter Changed - Unable To Change Back?

Aug 21, 2012

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.

Disk Management - Chg Drive Letter-disconnected Drive

Jun 18, 2009

My backup software's profile database is expecting to backup to H:, which was the drive letter for my external backup drive back in XP. This drive comes up in Windows 7 as K, because Windows 7 has given my four usb card reader drives the letters F,G,H,I.

Disk Management will not show these four card reader drives unless media is inserted (connected vs. disconnected). I have changed the letters for F,G,I to T,U,W, but only because I have those types of cards (SD, CF, MS)...I do not have an XD or SmartMedia card for the one dang drive I really need to change.

What are my options, other than buying the cheapest SM card I can find to make the drive visible for this task? The SmartSyncPro database has many profiles, so remapping all those to point to K would be a major hassle.

Laptop Becomes Unusable After Boot?

Feb 20, 2012

After I logon to my Windows 7 machine, the computer seems to freeze. Every once in ahwile I'll be able to do a little but it is painfully slow(3-5 mintues for one action). Everything runs normally in safe mode.Originally I thought my virus software of kaspersky 2012 was causing problems at startup, so unwisely I removed it. I can't get the machine to run long enough to get it reinstalled.The computer will start and run in safe mode. I have downloaded combofix. It runs and creates the log. It runs at an acceptable speed in normal mode after the combofix reboot where it is creating the log. However I can't launch any program because it says that a registry is marked for deletion. When I restart it goes back the computer being unusable.

IE 9 Completely Unusable - Every Website Will Freeze

Jul 12, 2012

i am having a serious problem with internet explorer 9 every website i go onto will freeze i will have to recover it numerous times until its working again, i thought it may be a flash problem cause i couldn't play Internet videos page kept crashing, and websites that have a flashed based ad on them where crashing but i've uninstalled flash player and reinstalled, it's the most up to date, i have disabled the hardware acceleration option as thats been mentioned on other boards but the problem still exists.

i had to recover this webpage twice to get it working. i have ran malwarebytes and superanti spyware, as well as windows defender, malware bytes and sas both picked up trojans which have been removed and subsequent scans have revealed nothing else, so i am at a loss as to what may be causing this problem, its the same problem on chrome aswell. sometimes a video will play then the next one won't.

Laptop Is Sluggish To The Point Of Being Unusable?

Sep 10, 2012

In short, my Dell Latitude E4310 laptop is sluggish to the point of being unusable. I am also unable to keep the Windows Defender service running.

Last week I had a blue screen error (code c000021a), presumably resulting from an improperly applied Windows update. I was able to return to an earlier instance of Windows and successfully apply the patches.

Here's what I've checked / done (not necessarily in this order).My BIOS is the most recent (A11), and BIOS diagnostics come up clean. Several safe mode virus & malware scans have come up clean. Windows Start-up Repair found no problem. I've run a clean boot to no avail -- Advanced Search The power plan seems normal, and I've (temporarily) uninsalled all anti-virus & malware programs. I've run disk clean-up and defragged the hard disk System properties, Advanced, Performance, Settings is set to 'Adjust for best performance' My Windows Experience Index scores range from 6.9 (processor) to 4.1 (graphics). Running a Windows System Health Report doesn't return anything. CHKDSK (right-click c:, properties, tools, error-checking) did find and repair some HDD errors. I'd attach the CHKDSK and WININIT logs, but neither is to be found in either my or the Admininstrator event logs. I've run SFC.EXE three times, and each time the verification only gets to 10% then fails, stating the following: "Windows Resource Protection could not perform the requested operation."

The SFC log looks normal save for the following: 2012-09-07 22:30:28, Info CSI 00000023 [SR] Cannot verify component files for b10e9bd0c69db5027b503ea3749c28f3, Version = 6.1.7600.16820, pA = PROCESSOR_ARCHITECTURE_AMD64 (9), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, PublicKey neutral, manifest is damaged (FALSE).
