Or even simpler so long as the original drive is no larger than the (temporary) 80GB replacement drive:

Connect both drives to a machine running Linux, figure out which drive is which in Linux (either "lsscsi" or "blkid" command), and then clone the original to the new one:

sudo cat /dev/sdX > /dev/sdY ## Takes a very long time

Then just plug the new drive into the empeg and see what happens.
