I had the same problem. Thanks to John's computer management hint, I
was able to determine what the issue is with my system. It turns out
that XP wants to assign the next drive letter after the last PHYSICAL
drive assigned. However, I already had network shares mounted on the
next two drive letters, and it would be a major pain to change them.
So my last physical drive is D:, and XP put my lexar drive at E:, even
tho I already had network shares on E: and F:. As soon as I used
computer management to change the drive letter on the lexar media to
G:, everything works. I only hope this config lasts over a reboot, but
if not, it's an annoyance, not a big problem.
Hope this helps...
