Other Problems and Solutions
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).
Notice
If both SCSI and non-SCSI (e.g. IDE) disk drives are installed, then the non-SCSI
disk drive is always the boot device.
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
SCSI Select.
– 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.
