But which drive is the problematic one? You never explicitly mention that. Then you proceed to post xxd dumps of sdb(!), and also "strings | grep" and partition listing of sdc(!!!). So which is it, sdb or sdc, or are you unsure at this point. Also post stuff directly to the mailing list, as websites go away with time, whereas the mail archives can be more resilient. (Not to mention asking thi= ngs like these on "stackoverflow" is a bit like expecting a useful answer on Ubuntu Forums). --=20 With respect, Roman --Sig_/H+R_XGZBD6iYoFEaiursNNL Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlYGTVIACgkQTLKSvz+PZwjUVwCdGW58Wmqos2ehmKTEK9F1jLit IYoAnikhlJsM+sVyXI1SvqApeJFJ8VTI =er6G -----END PGP SIGNATURE----- --Sig_/H+R_XGZBD6iYoFEaiursNNL--
