I hate to be the bearer of bad news, but whatever disk is reporting the bad blocks probably needs to be replaced. Modern disks have the ability to remap sectors automatically. If you are getting bad sectors during writes, it means that the remapping table has been exhausted. If you're getting bad sectors during reads, your best bet is to try to copy those blocks elsewhere and hope for the best. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.19 (Darwin) iQIcBAEBAgAGBQJT2l/1AAoJEB57S2MheeWyt80QAKqaMGAS8rsWOeSi4fN0rRdR /pKoPOEIub/lIwVxct6wGyut5+D+11ihLDUTnZnskImq3l+uEZQuOXTzY57CbTeW 34W8e5hZoUTb4fNXONYyIPrq6RsiLC82Hixkbt90A7V9r/zpyu0uMwqwHqtjfP3l QQw+IoucdxXdKn0d0udNfWZF9UbV9lNYQtBDCtz/7YGwf249al3dJfzuI0fx9gJ6 0OSZboMeVYfzJ53bmi8NDMVACz75y9E8x5DJX40NgBZNB9TpahCK0ttCSJ3n5v8D CvEAGeUEThoJtMVcT93zRzLAky8AHOTQVS+OLNdbHm8eGKYULlbyJdNDFVo6q0/r QM1wFPolnZCOOKnRW9JciG/ZJl1KRK38U1ad+e42PblDZs/hZU3mixhT/zgf4gWd d2oG3AoDlSm2gxORq5Nf8Af9kxbSi55Rx/LuDB+DrW83nKlk6fbAM+zA2cBDbZjN 84wh9xLmBWjsUkSPXcSvhWUjI5saBoxBXG7VO6lO6dOAkpP/QMwi2dgcuzEpuheS GINBUwGiPx1PLuwKXEZ3ho7cAarLbJ7j/u5YZdZ4MGeUGzkDsHsYQTN2epSe8RB8 cDJdTForsiWlxegiJV/1CPkFQkZONomEW5xqjjByCtNG4eKX5EEp8c7VLDu1n/FV n5h2M9zt4EmW705M9nPf =iHxa -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe reiserfs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
