Does the external drive have its own power source? I've had some issues
with external drives that don't have their own external power sources. I
can usually get them to work by trying different USB ports. For some
reason USB hard drives (not flash drives) without power supplies do not
always function properly on all of a machines USB ports. I would try
each USB port one by one and fdisk -l, giving the drive about 30 seconds
to settle after being plugged in. Hopefully it will come up on one of
the ports.

Also check the output of "dmesg | tail" after you plug it in and see if
you get any messages about the drive.
