Drive letter nightmares


Recommended Posts

Posted

I have two internal harddrives using NFTS file system, split into five

volumes. PC was working great, until the other night when attempting to

shut down the pc... it wouldn't it would just hang. This afternoon - after

getting tired of this $^#% - I booted from a XP Install CD and selected R

for repair. When I was asked which install of windows I wanted to repair it

was displaying 1.D:\Windows. It should be C:\windows.

 

Using Map I looked at all the drive letters on the PC.

I know my C: Bootdrive should be 104 GBs C is being reported as G, and D: is

only 15.6 GB in size.

 

The order of the drives was: A,B FLoppy disks

C: D: E: [harddisk 0/Parts 1 -3], CD drive F:, DVD G:, H: and I: are

harddisk 1/ part 1 -2 . (slaved)

 

Its like everything is back to front.

Re: Drive letter nightmares

 

Try not to mix up the terminology. You have two physical drives. One has

two partitions on it and the other has three partitions on it. Drive

letters are assigned to the partitions, not to the physical drives. This is

done in some specific way that may vary from one brand of BIOS to another.

C: drive is typically the active partition on the first hard drive in the

boot order which actually has an active partition. So if the first hard

drive in the boot order does not have an active partition, then C: could be

assigned to the active partition on the second drive. I don't know which

letters would be assigned to which of the rest of the partitions. In the

bios, you can typically change the order in which the physical drives are

checked for whether they have an active partition to boot from. So in the

bios, find the option for changing bootup order, and put the physical drive

you want to boot from ahead of the drive you don't want to boot from. Be

sure to save on exit from the BIOS setup window. Hopefully these drives

have a physical capacity or brand difference so you can tell which one you

actually want to boot from. When you boot up, the partition which is

assigned the letter C: should be the partion on which you originally

installed Windows, and perhaps all will be well. Let us know how it goes.

Click Start / Run / diskmgmt.msc{Enter}. You can now

right-click the various drives and re-assign their drive letters.

It may be necessary to reboot the machine a few times until

every letter is in place.

 

Post again if your system drive letter is incorrect. There are

ways to fix this too. If you do, make sure to post an exact

map of your current and your desired configuration, e.g.

like so:

 

Current Configuration

==============

Drive C: Label=System Size=100 GBytes

Drive D: Label=Data Size=50 GBytes

etc.

Hi Pegasus...

 

I think I may have been a bit premature believing there was a problem with

drive letters. After setting chkdsk/ f from a command line, I powered down

the system for awhile, and then restarted after a few hours. chkdisk fixed

some empty entries:

Windows has finished checking your disk.

Please wait while your computer restarts.

 

 

Disk manager now once again displays the proper drive partition information.

 

Another thing I did was invoke msconfig, and I took a look at whats going on

in Boot.ini

what I saw was:

 

multi(0)disk(0)rdisk(0)partition(1)\Windows="Microsoft Windows XP

Professional" /noexecute=optin /fastdetect.

 

Use edit I swapped the delimited items around, and this seems to have fixed

a couple of problems. I'm at a loss to explain how the /noexecute and

/fastdetect items got swapped.
