Don't bother re-installing SAS; instead re-create the data sets.

They're hosed.

You may, in fact, wish to check out the other files on this drive; back-up the good ones and then re-format (i.e., start w/ a low level, device format which will block-out bad sectors/tracks) this drive; I suspect it is beginning to die as I recently had the same experience w/ a 36GB U160 SCSI drive.

All this assumes you have more than just C; otherwise you might be re-installing everything <g>
