I have a 3TB Hitachi HD () which progressively 'lost' displayed capacity to currently just above 740 GB.
Explorer, Installation-DVD and harddisk manager (win7) all agree on this size @ 1.5 billion LBAs.
I downloaded various HDD tools mainly from HDDGuru.com, the most promising for my problem seems to be HDD Capacity Restore, but it does not support win7. When run 'compatibly' (XP SP3, admin rights) it warns 'error loading driver' before start. and shows only scrambled data on all controller buses.
Is there another tool for Windows 7 or Ubuntu, or even a third way to reset the disk?
