2TB RAW (Corrupted) exFAT drive

#1 Post by WastedPenguin » 25 Oct 2013, 19:04

Hi,

I have a problem. My 2TB hard drive has broken again. It is the WD Caviar Green WD20EARX 2TB edition. In the past I had exactly the same problem (he could no longer read under Windows and Mac), and then solved it with TestDisk. The problem then was in the boot sector. I used the super backup from the drive and magically it's worked, but this time it seems not to work. The drive itself is formated as exFAT.

I hope somebody can help me out here, since I don't have another drive to backup stuff.

I use Mavericks (10.9) with Windows 7.
