Are you in graphics mode at the time?
Have you tried using Ctrl+Alt+F1 to switch to a text terminal, then
plugging in the USB device?
I suspect you're getting a kernel panic. In such cases Linux *won't*
write to disk (it's no longer sure that kernel memory is in a sane
state, so it isn't sure that the disk routines won't write Rhapsody in
Blue over the partition table).
The Linux kernel will write kernel panic data onto a text terminal. But
it doesn't know how to do this if the console is in graphics mode.
You can use Shift+Page UP and Shift+Page Down to scroll through the
kernel panic data. Take a photo of it, or write it down.
If you do get a kernel panic, please bugzilla it, and include the data
you copied from the screen. (Use http://bugzilla.redhat.com). Then the
appropriate developers should get to see it.
Hope this helps,
James.
