Barracuda 18XL Product Manual, Rev. A 1
1.0 Scope
This manual describes the Seagate Technology®, Inc. Barracuda 18XL™ disc drives.
Barracuda 18XL drives support the small computer system interface (SCSI) as described in the ANSI SCSI,
SCSI-2, and SCSI-3 (Fast-20, Fast-40, and Fast-80) interface specifications to the extent described in this
manual.* Ultra, Ultra2, and Ultra160 are the names Seagate calls these interfaces. The SCSI Interface Product
Manual (part number 75789509) describes general SCSI interface characteristics of this and other families of
Seagate drives.
From this point on in this product manual the reference to Barracuda 18XL models is referred to as “the drive”
(unless references to individual models are necessary).
