[PDE]

I just got a new seagate freeagent pro to back up my macbook pro and macbook. I partitioned the drive into three sections - cloned my MBP hard drive to the firs partition and had no problem booting off it. Then I backed up my macbook hd to the second partition. Seemed to go well, but when I booted from the clone I got to the desktop and the finder keeps crashing. The menu bar just blinks on and off and when I try force quitting, I see 'Finder" appear and disappear - so I assume it's crashing. In any case, I can't access any menus or anything and have to force a shut down.

Any ideas?

Thanks
