Yes this drive has it's own power supply. Yes I plug in the external power supply before connecting the USB connector.
Sometimes the drive mounts without a problem. When I try to copy more than a few MB of data it un-mounts itself and generates an error. 
What I'd like to do is have a entry /dev/sdb1 and have it not mounted so I can fsck. I think if I umount /media/backup it will also delete the /dev entry.
