The only time I've run across SCSI errors is on a Jaz drive (and then
frequently). My experience is that once I reach the stage of sense
errors, the drive's days are decidedly numbered. Move what you can
elsewhere and scrap the disk, IMO. If it's warranteed, you might want
to check into getting a replacement. Most media these days carries an
extended guarantee period.
