Product Manual - Hawk 2LP Family (Wide) 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 as described in the ANSI SCSI-1, SCSI-2 and
SCSI-3 Interface Manuals to the extent described in this product Manual (Vol. 1), which defines the product
performance characteristics of the Hawk 2LP (Wide) 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 2LP Family (Wide) 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 2LP Family (Wide) 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 2LP Family (Wide) drives decode track location from the dedicated servo surface to eliminate
mechanical transducer adjustments and related reliability concerns.
The Hawk 2LP Family (Wide) 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.
