Drive C: is not recognised by drive A:

[salterre]

After booting from A:and I try to access C: by typing C: I get the
message: "invalid drive specification". There is no way that I can
access drive C: from A:, yet, everything is OK within the Windows XP
environment both drives are accessible fom one another.
Also a Maxtor external hard drive which was working OK has stopped
being recognised by the system; I get the message: "USB device not
recognised"; in Device Manager any of the Bus Controllers where the
external drive is connected is marked "Unknown device". All other
devices are recognised.
I am not quite sure but I became aware of this problem soon after I
installed "Norton Go Back".
I reinstalled Windows XP and also updated the system BIOS, but the
problem still persists.
Has anybody experienced the same problem, or have an idea of what may
be the cause and what can be done to fix it.
Please, I really need help.

If you are booting from a W98 boot disk and your C: drive is in NTFS format
then you will get the result you describe. Dos only recognises FAT drives
AFAIK.....

You "did" uninstall Norton GoBack before you reloaded the operating system -
as the GoBack instructions tell you to do, right?

I did not uninstall Norton Go Back, nor any other applications,
thinking that reformatting the hard disk would wipe everything out, if
that was not the case is there any way to fix the mistake ? Can you
tell me what I can do ?

[salterre]

you are right, I got the message.

If you reinstalled without uninstalling GoBack first (as per the GoBack
instructions) you will need to repair the MBR to remove all remnants of
GoBack.

Your answer is positive, you are pointing at a definite spot in the
system; repairing the MBR sounds difficult but if you can tell me how
to go about I will certaily try to do it.

I can tell you how to repair the MBR but first I must state the following.
If drive C: is formatted as NTFS you will NOT be able to see the drive from
any DOS program. You see, you may have 2 problems/conditions.

To repair the MBR, get hold of a Windows 98se setup floppy. Boot the
computer from this floppy. When you get to the A:/ prompt, type in "fdisk
/MBR" without the quotes. This will repair the MBR on drive C:, and drive C:
only. When done, reboot the computer. You will now have a stock Master Boot
Record without any trace of GoBack in it.

After you have repaired your operating system, you may again install GoBack.
