USB flash drive 'not formatted' error

[Dave]

I have WinXP SP2. Just recently started getting an error whenever I install
any USB flash drive. The drives get the USB Mass Storage Driver installed
and get a drive letter. But Windows Explorer cannot open the drive. An
error window opens stating "The disk in drive X is not formatted. Do you
want to format it now?" I can use the flash drives successfully on other XP
systems so the problem must be with my system.

I removed the usbstor.sys driver, rebooted, and the new copy of the driver
did not fix the problem.

(Previously posted this in Hardware discussion group but no replies.)

Does anyone have any ideas? Thanks.

I get the same thing when I use a SD card larger than 1GB on my Gateways.
Although no problem when I use them on my Asus EeePC SD slot. As they can
read up to 32GB SD cards. If you are using a card reader, some card readers
have the same problem as my Gateway built in SD card reader does. Although I
can read the cards just fine with a card reader that can handle larger SD
cards.

I know that in this case my flash drive is not too big. I had previously
been able to use it on my system. I suspect that a Windows Update or some
such thing has whacked the USB Mass Storage driver or something such that I
can't get at the contents. Unfortunately, I don't use a flash drive often
enough to be able to pinpoint when the problem began.

How old is this flash drive? And how big is it?

My primary flash drive is a SanDisk cruzer micro 1.0GB. It works fine on
any other PC. Any other flash drive I try also fails with the 'not
formatted' error including the following:
Lexar JumpDrive 512MB
HIMSA drive - unknown size

Maybe this will help.

You may have a hardware failure of your I/O chips too.
