Product Manual - Hawk 1LP Family SCSI-2 (Volume 1), Rev. A 3
_____________________________________________________________________________________
3.0 General description
The drives are a member of a family of low cost, high performance, highly reliable, random access storage
devices designed to meet the needs of the OEM marketplace.
The drive records and recovers data on 3.7 inch (95 mm) fixed discs.
The drive supports the Small Computer System Interface (SCSI-2 and SCSI-3) as described in the ANSI
SCSI-1 and SCSI-2/SCSI-3 Interface Manuals to the extent described in this product Manual (Vol. 1), which
defines the product performance characteristics of the Hawk 1LP Family of drives, and the SCSI Interface
Product Manual P/N 77738479 (Vol. 2, Version 2) which describes the general interface characteristics of this
and other families of Seagate 3.5-inch drives.
The drive interface supports multiple initiators, disconnect/reconnect, self configuring host software and
automatic features that relieve the host from the necessity of knowing the physical characteristics of the targets
(logical block addressing is used).
The Head/Disc Assembly (HDA) is environmentally sealed at the factory. Air recirculates within the Head/Disc
(HDA) through a nonreplaceable filter to maintain a contamination free head/disc environment.
Refer to Figure 3.0-1 an exploded view of the drive. NEVER disassemble the Head/Disc Assembly (HDA). This
exploded view is for information only. Do not attempt to service items in the sealed environmental enclosure
(heads, media, actuator, etc.) as this requires special facilities. The drive contains no parts replaceable by the
user. The drive warranty is voided if the HDA is opened.
The Hawk 1LP Family drives use a dedicated landing zone at the innermost radius of the media to eliminate
the possibility of destroying or degrading data by landing in the data zone. The drive automatically goes to the
landing zone when the power is removed.
The Hawk 1LP Family drives incorporate an automatic shipping lock which prevents potential damage to the
heads and discs that result from movement during shipping and handling. The shipping lock is automatically
disengaged when power is applied to the drive and the head load process begins.
The Hawk 1LP Family drives decode track 0 location from the dedicated servo surface to eliminate mechanical
transducer adjustments and related reliability concerns.
The Hawk 1LP Family drives use a high performance actuator assembly that consists of a low inertia, balanced,
patented, straight arm design that provides excellent performance with minimum power dissipation.
