The following tables list the values of the data bytes returned by the drive in response to the Mode Sense com- mand pages for SCSI-2/SCSI-3 implementation (see the SCSI Interface Product Manual, part number 75789509).

Definitions:

DEF = Default value. Standard drives are shipped configured this way.

CHG= Changeable bits; indicates if current and saved values are changeable.

Note. Saved values for OEM drives are normally the same as the default values.
