Other Problems and Solutions
Note
If both SCSI and non-SCSI (e.g. IDE) disk drives are installed, then the
non-SCSI disk drive is always the boot device.
RI 45 PIII, Manual
C79000-G7076-C817-01
If you are booting from a SCSI hard disk drive, make sure the Drives
setting (in your computer's setup program) that corresponds to the drive is
set to None or No Drives Installed, as is required for SCSI hard disk
drives (for further information, refer to the documentation for your
computer).
If you changed any values on a host adapter, in a setup program, or on a
SCSI device, did you turn the power OFF and ON to ensure that the new
values are loaded?
If you tried to use the format/verify utility on a disk device and got an
Unexpected SCSI Command Failure pop-up bow with error information,
the utility probably encountered a problem with the disk device or the
media and therefore cannot run.
You can probably determine from the Sense Key information (e.g. 06h –
Unit Attention) both the cause of the problem and its solution. Here are
some of the more common Sense Key values and their meanings:
– 02h – Not ready – The media is not ready to format. Be sure that
media is inserted in the drive and that the media is spun up.
– 03h – Medium error – The disk media may be defective. If it is a
removable-media drive, try using a different disk media. If it is a fixed
disk drive, the disk may be physically damaged. Verify and format the
media with SCSISelect.
– 04h – Hardware error – The disk drive may be defective. Consult the
hardware documentation and contact the manufacturer.
– 05h – Illegal request – The Adaptec formatting utility does not support
a low-level format of this device; however, the device may already be
low-level formated by the manufacturer. (This error rarely occurs).
– 06h – Unit attention – The removable media may be write-protected.
Disable write protection and run the utility again.
