I have been searching in Knowledge Base about this problem and still haven't
got any answer!

I tried to connect a new removable drive (80GB 2.5" Harddrive using USB
interface - the power is surged from USB interface) into both of my laptops
(both are using XP home edition - Genuine - XP2 with all the latest update).
When I was initiating drive and formatting the new drive (the drive was put
into primary drive and NTFS system), the drive was detected very well. The
drive was well-formatted but when I went to Windows Explorer, it didn't show
me any letter that I had been assigned for the drive. I rebooted my laptop
and It booted until desktop screen and initiation of removable drive and then
it just hang (black screen on my laptop without any more informations). It
continued happening with all the USB ports that I have on my laptops.

My question is Is it because of low voltage issue? FYI, My laptops are using
Centrino and Centrino duo processors or Is it a driver compatibility issue
because of I could read the drive before the formatting session and couldn't
do that afterwards (it went to black screen)?

Anyone has a clue?

Regards,
Mika KADRIE

When you write "the power is surged from USB interface", do you
mean that the power is supplied from the USB interface? If so then
this may be the cause of your problem. Some 2.5" disks draw too
much current, hence they often come with a cable that has two USB
connectors: One for signal+power, the other just for extra power.

You should also try and connect the disk ***after** you reached
the desktop, not at boot time.

You could have one of several defects:
- Faulty USB port
- Faulty USB cable
- Faulty disk
- Faulty USB case

To home in on the cause of the problem I would
connect the disk to some other machine.
