I you have an Adaptec card, you may want to check the disk using the utilities provided with the card to test the disk (alt-A at boot time before linux is booted). You can also check the grown defects list with the MS-Windows utilities provided with EZSCSI. Don't know if there is some linux utility providing the same functionality. good luck! lazaro <[EMAIL PROTECTED]>

I believe your disk is telling you that it tried to write to a sector = but that when it went to read it back to verify the data written was = correct, the verify failed. Typically SCSI disks will then automatically = reallocate the bad sector with some reserved sectors at the end of the = disk.

If this is the case and you're consistently seeing these messages, I'd = say your disk is spiraling downward. Eventually the disk will run out of = sectors to re-map and a SCSI write will fail. If Linux does not support = its own remapping on failed writes (does anyone know if it does?) you'll = probably get a panic, your system will halt and you'll probably have a = hell of a time trying to repair the volume and remount it to back it up.

It's an old Fujitsu that I bought used 2.5 years ago and it's been running non-stop since.
