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 Xin LI http://www.delphij.net/ FreeBSD - The Power to Serve! --------------enig10974C634FBC4BDAE1646FE6 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFH9sG9OfuToMruuMARCr4pAJ0XbDFbuPfE4iSmGNrgCU3OnRcUsQCghUNp pR/grkx0RqOimQacvvIUvbo= =4vuQ -----END PGP SIGNATURE----- --------------enig10974C634FBC4BDAE1646FE6--
