Hi, a friend of mine just overwrote two months of her PhD thesis with
13 1 Steve Welburn
an older version. I know recovery of overwritten data is possible, but
14 2 Steve Welburn
wonder if I'd need special hardware to do it. Does anyone know
15 1 Steve Welburn
something about this ?
16 2 Steve Welburn
Thank You.
