You should probably look on Quantum's ftp site and see if there is any updated firmware for the drive. They released updated firmware for the Atlas II (LYK8) that fixed the hanging problem, and it's possible there may be newer firmware for that disk. > Is there any way to test the individual disks-defects "through" the DPT > controller? > [~wjw] root@hobby> scsi-defects /dev/rda1 Plist > SCIOCCOMMAND ioctl: Inappropriate ioctl for device > There are no defects (in this list). Well, that's an old script, written for the old SCSI layer's userland interface. Try 'camcontrol defects', like this: camcontrol defects -n da -u 0 -f phys -PG If you look at the camcontrol(8) man page or 'camcontrol help', you'll see more information about the defects command.
