Device is defect, errror code 0X22.
This weekend my harddrive crashed badly. Did I have a backup? Yes I did. I finally had use of my backups. So the todays lesson is, make backups, often.
Update: Seemed that it was not a hard disc crash, it was the PSU that did not work correctly. After buying a new one the problem vanished. Strange thing though, the new disc that I bought was mail functioning from the beginning. This made me scratch my head a few times. Even strangier is that the new disc that I bought seemed to be an old disc. It had a bunch of scratches on the side. The plastic bag that the disc laid in was new. Does Seagate re-package old discs they get back and sell them as new?
