Hmmm, Odd. I do a lot with both external USB 2.0 HDDs and I read/write
a lot of 1-2GB CF cards. I've never experienced this sort of lockup.
Maybe I've just been lucky. I've done this with Suse, Ubuntu, & Fedora
on a variety of boxes ranging from my own company's USB 2.0
implimentation, to Nforce based MB chipsets, to whatever flavor of the
month Dell decided to put in the box I've got to work on this week. Is
there a specific pattern of activity you could follow to get the failure
to occur? I'd love to test my HW with it if so.
