Hi,
Recently my hard drive goes bad again, which has a lot of bad sectors=20
for unknown reasons. I am looking for some software that is capable of=20
doing a sector-to-sector copy of the hard drive.
I have tried dd but with conv=3Dnoerror,sync it would just fill 0's for=20
the whole block size (say, in order to get best speed you will want=20
bs=3D128k or even larger, but that means that you will lose data when 1 =
of these 256 sectors is bad). Is there any program that is smarter=20
which do a sector-to-sector copy for these failed blocks and use larger=20
transfer buffer for others?
Cheers,
--=20
