Hmm, yeah possibly. Unplug the USB drive, wait a bit, then plug it back 
in. Then unmount all the partitions on it first, before running fdisk. 
(You can do that with "sudo umount /dev/sdb1", "sudo umount /dev/sdb2", 
etc. until all the partitions are unmounted. There's probably going to 
only be one partition on it.)
