3.1 Standard features
The Cheetah 36ES family has the following standard features:
• Integrated Ultra160 SCSI controller
• 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 4,096 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)
• Enhanced ECC maximum burst correction length of 240 bits with a guaranteed burst correction length of
233 bits
• 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
• 1:1 Interleave
• Zoned bit recording (ZBR)

• Dynamic spindle brake
• 4,096 kbyte data buffer
• Hot plug compatibility (Section 9.6.4.2 lists proper host connector needed) for LC model drives
• Drive Self Test (DST)
3.2 Media characteristics
The media used on the drive has a diameter of approximately 375 inches (95 mm). The aluminum substrate is
coated with a thin film magnetic material, overcoated with a proprietary protective layer for improved durability
and environmental protection.
