Cheetah 15K.5 SCSI Product Manual, Rev. D

Cheetah 15K.5 SCSI 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 power is removed.

An automatic shipping lock prevents potential damage to the heads and discs that results from movement dur-
ing shipping and handling. The shipping lock automatically disengages when power is applied to the drive and
the head load process begins.

A high-performance actuator assembly with a low-inertia, balanced, patented, straight-arm design provides
excellent performance with minimal power dissipation.

3.1

Standard features

The Cheetah 15K.5 SCSI family has the following standard features:

• Perpendicular recording technology.

• Integrated Ultra320 SCSI interface.

• Multimode SCSI drivers and receivers—single-ended (SE) and low voltage differential (LVD)

• 16 bit I/O data bus

• Asynchronous and synchronous data transfer protocol

• Firmware downloadable via SCSI interface

• Selectable even byte sector sizes from

512 to 528 bytes/sector

• Programmable sector reallocation scheme

• Flawed sector reallocation at format time

• Programmable auto write and read reallocation

• Reallocation of defects on command (post format)

• ECC burst correction length of up to

400.

• Sealed head and disc assembly

• No preventative maintenance or adjustment required

• Dedicated head landing zone

• Embedded servo design

• Self diagnostics performed when power is applied to the drive

• Zoned bit recording (ZBR)

• Vertical, horizontal, or top down mounting

• Dynamic spindle brake

• 16,384 kbytes data buffer

• Hot plug compatibility (Section 9.6.4.2 lists proper host connector needed) for LC model drives

• Drive Self Test (DST)

• Supports SCSI bus fairness

3.2

Media characteristics

The media used on the drive has an aluminum substrate coated with a thin film magnetic material, overcoated
with a proprietary protective layer for improved durability and environmental protection.
