USB mount problem

[Guest]

I have a 200GB external USB drive that has been working fine for ages. I use
win32xp on my laptop and often power down / power up using hibernate, not a
full reboot (I do reboot too every so often).

For the past day, my USB drive has not been recognised when I plug it in.
The hardware is fine as it works just right on other PCs. Using a different
USB port doesn't help. It doesn't show in device manager, never mind in my
computer.

How can I get windows to recognise my drive ?

Maybe this helps...

Create a system restore point first...

To make the device manager show non present devices, we
need the environment variable DEVMGR_SHOW_NONPRESENT_DEVICES
set to "1".
The easiest way is to start the device manager using a
command script. Put the following two lines into Notepad
and save as DevMgmtX.cmd

set DEVMGR_SHOW_NONPRESENT_DEVICES=1
devmgmt.msc

Start the saved DevMgmtX.cmd, the device manager comes up.
Select 'View' -> 'Show hidden devices'.
Now delete all non present stuff (translucent icons)
under 'drives' and 'storage volumes' and all 'USB mass storage'
under 'USB controller'.
