Hi, I have had this with a drive and multiple read errors would not remap the sector. With write errors the sector would be remapped. This was a new Samsung laptop drive though, not a Western Digital. To get the sector remapped I had to fully write the drive and it was ok after that. For now no bad sectors have been showing up Disclaimer: http://www.ose.nl/email _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
