Since a few days ago, my computer freezes while I sync my internal hdd with an external WD Passport 1TB drive (3months old). When the keyboard gets temporarily a bit responsive I am able to switch to another terminal (Ctrl+Alt+F2) and I see the following image repeating continuously. I am on Ubuntu 11 using LuckyBackup.

What is going on? Is my hdd defective? Is it the external one? Something else?

For one thing Ubuntu is not in the list of approved OSs on most of these external drives. Find your drive and look at the list of OSs.

Go into a Windows computer and test your drive with the Western Digital DLG diagnostic software.
