reformatting a scsi disk will totally erase a disk!, and the best way
to perform a low level format is to use scsi utilities (either in the
controller bios or on disks with the controller) .
As for SCSI error messages, are you sure its not a loose cable, long
or damaged cable, bus configuration error or incorrect termination.
badtrk will also give you options for out mapping bad sectors on the
disk - saves reformatting!.
