9.0Interface requirements

This section partially describes the interface requirements as implemented on the drives.

9.1General description

This section describes in essentially general terms the interface requirements supported by the Cheetah 73LP. No attempt is made to describe all of the minute details of conditions and constraints that must be considered by designers when designing a system in which this family of drives can properly operate. Seagate declares that the drives operate in accordance with the appropriate ANSI Standards referenced in various places herein, with exceptions as noted herein or in the Seagate SCSI Interface Manual, part number 75789509.

9.2SCSI interface messages supported

Table 4 lists the messages supported by the SCSI-2 and SCSI-3 modes of the Cheetah 73LP family drives.
