A 2Gb system SCSI disk on an Adaptec 2940, running Freebsd 2.1, has
developed at least one bad sector. The kernel prints the message:
Feb 18 20:53:48 rna /kernel: sd0(ahc0:1:0): MEDIUM ERROR info:333aca asc:11,0 Un
recovered read error field replaceable unit: d0 sks:80,29
How you read the above message ? Which are the bad sector numbers ?
I would rather not have to re-SCSI format this disk. What can I do ?
There should be a way to bad-sector replace the bad sectors with alternates ?
What utilities do I use ? Thanks. Please email.
Cheers,
