CRUNCH! OUCH! R/W ERROR! This is utter nonsense! The driver will only access blocks that have been requested by the filesystem. There is NO WAY a SCSI host adapter's driver could step a drive's heads outside the valid range - SCSI isn't ST-506 or trackdisk.device! Something like this could only be done by the SCSI drive controller's firmware. And even _if_ an invalid block would be requested, then the drive is supposed to reject this request with an error.
