It is likely that the disk has one or more bad blocks. Use `smartctl -a /dev/sdx` to see all the data (or -A to see only the attributes) and look at the raw values of Current_Pending_Sector and Reallocated_Event_Count. The first reflects unfixed problems, and the second fixed problems. If both numbers are low, I would just keep using the drive, though I would first do a long test with `smartctl -t long /dev/sdx` (wait until the indicated time and then do a `smartctl - a /dev/sdx` to see what happened) and then enabled Automatic Offline Testing with `smartctl -o on /dev/sdx` (this will help keep up with sectors as they go bad, without unnecessary data loss). A program such as ddrescue (`yum install ddrescue`, `info ddrescue`) may help to salvage the damaged file(s). -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/> -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
