External Hard Drive, Maxtor

I have had a Maxtor 3200 USB disk drive working on my laptop for the past 2
years.
Yesterday I booted the laptop and the maxtor was not recognized by
Windows XP when I went to use the data on the USB drive. I tried another
maxtor and under USB devices, I have a yellow warning on the USB Mass
Storage Device and when I opened it, Windows told me that I had an Error
Code 10, device could not be opened. I then restored my system from 3 days
ago and had same problem. I then uninstalled SP 3, which was just installed
3 days ago. No luck with either attempted fix. I deleted all USB devices in
Device Manager and rebooted. No luck again. I then took the first maxtor
and mounted it on a non-updated with SP 3 desktop machine, and the disk
came up without any problems or any loss of data.
I am out of options now. I have called the maxtor, no ideas,
or solutions. I have called the computer manufacture and no ideas or
solutions. I am now at Windows XP site and no one here seems to have a
solution.
