I've been trying to back up my hdd onto an external drive using superduper. When the program runs it executes the preparation steps including repairing disk permissions and wiping the external drive fine. Then it begins copying data. After about 4 minutes it has moved around 580 mb of data but at this point it stops. Twice i've let it sit for over half an hour and the tracker still reads 580 mb. The timer keeps going in the bottom and the program still looks like its running but it just stops operating as far as I can tell.
Anyone ever heard of anything like this?
