I've tried on 3 occasions tonight to back up my files etc. Every time is whizzes through the first bit, gets to about 12/13% completion and seems to hang. Whilst it was in this state there was no HD activity light, and I checked task manager, processes, and the backup process was showing zero CPU usage and memory use was static.
Should I just leave it on overnight and hope it has completed by morning. Surely simple file copying from one drive to another shouldn't take so long ?
