This manual describes Seagate Technology® LLC Cheetah 36XL™ disc drives.

Cheetah 36XL drives support the Small Computer System Interface (SCSI) as described in the ANSI SCSI interface specifications to the extent described in this manual. The SCSI Interface Product Manual, part num- ber 75789509, describes general SCSI interface characteristics of this and other families of Seagate drives. The SCSI Interface Product Manual references information from the documents listed in Section 2.3.

From this point on in this product manual the reference to Cheetah 36XL models is referred to as “the drive” unless references to individual models are necessary.
