A couple of random things you might try:

Have you tried all your USB ports? Occasionally, the ports on the
backplane (near the keyboard and mouse PS/2 ports) work better than
those on the front of the machine.

Try, as root, running
/sbin/rmmod ehci
before plugging the disk in. This downgrades the kernel to USB 1.1, but
solves some issues.
