Well, a SCSI disk starting to show bad blocks is either : - a SCSI disk with automatic bad block remapping turned OFF, - a SCSI disk you should change at one if ON... Do the following command to see i automatic bad block remapping is ON or OFF: scsi -f /dev/rsdNc -m 1 If the two first parameters (ARWE and I keep forgetting the second) are both 0, then it is OFF. Turn them ON by issuing the following command, edit the two fields and save. scsi -f /dev/rsdNc -m 1 -P 3 If both are set to 1, then automatic remapping is already ON and the disk has no more available sectors to remap bad blocks into. Return it to your vendor to get another one. [ Cc:'ed to Joe ] -- Ollivier ROBERT -=-=- FreeBSD 2.x FAQ maintainer -=-=- roberto@freebsd.org -=-=-=-=-=- Support The Free UNIX Systems !
