The MEDIUM ERROR is generally an error message indicating a SCSI hardware problem. If this symptom appears on an old kernel as well be prepared to replace your hard drive. I have had several SCSI disks bomb over the past 2-3 years, and almost always preceeded by SENSE KEY MEDIUM ERROR when I run the adaptec diagnostics. I have often been able to re-map bad sectors with the adaptec off-line rom diagnostics (verify disk) but they seem to return on many drives. Check all cables and terminator's first, then see if you have any off-line diagnostic pgms that can re-map bad blocks. Sometimes a power loss at a critical time can also cause bad blocks which may be repairable by a low-level re-format.
