The sense code tables in the SCSI2 std standard indicate that the
asc/asq 09/00 "Track Following Error" might be used by direct and
sequential access devices. But the following ascs/asqs would not be
used by those devices.
09/01 "Tracking Servo Failure"
09/02 "Focus Servo Failure"
09/03 "Spindle Servo Failure"
I guess I can see why you might not get a "Focus Servo Failure" from a
disk drive. But why not the "Spindle Servo Failure" or "Tracking Servo
Failure"? If these aren't used by disks, then what sense codes would a
disk return for spindle speed errors?
