Most drives will reallocate a bad sector providing you write over it. fsck will do this for problematic metadata (block counts, bitmaps, inodes etc) if it has to. For data hdparm --repair-sector offers a very low level interface. As there is no easy way of finding out which file owns the problematic block or how many there are and which files they are in without accessing that bit of data a backup and restore is normally wise. When ever possible I use raid 1 (mirroring). Drives are fairly cheap, sizes are so big that capacity isn't a problem. Reliability without raid isn't good enough IMHO. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
