PRODUCT DESCRIPTION

Product Features

Functional / Interface
Maxtor DiamondMax™ 6800 hard drives contain all necessary mechanical and electronic parts to interpret control
signals and commands from an AT-compatible host computer. See Section 3 Product Specifications, for complete
drive specifications.

Zone Density Recording

The disk capacity is increased with bit density management – common with Zone Density Recording. Each
disk surface is divided into 16 circumferential zones. All tracks within a given zone contain a constant
number of data sectors. The number of data sectors per track varies in different zones; the outermost zone
contains the largest number of data sectors and the innermost contains the fewest.

Read/Write Multiple Mode

This mode is implemented per ANSI ATA/ATAPI-4 specification. Read/Write Multiple allows the host to
transfer a set number of sectors without an interrupt request between them, reducing transfer process
overhead and improving host performance.

UltraDMA - Mode 4

Maxtor DiamondMax 6800 hard drives fully comply with the new ANSI Ultra DMA protocol, which greatly
improves overall AT interface performance by significantly improving burst and sustained data throughput.

Multi-word DMA (EISA Type B) - Mode 2

Supports multi-word Direct Memory Access (DMA) EISA Type B mode transfers.

Sector Address Translation

All DiamondMax 6800 drives feature a universal translate mode. In an AT/EISA-class system, the drive may
be configured to any specified combination of cylinders, heads and sectors (within the range of the drive's
formatted capacity). DiamondMax 6800 drives power-up in a translate mode:
(*) The fields LZone (Landing Zone) and WPcom (Write Pre-comp) are not used by the Maxtor hard drive
and the values may be either 0 or the values set by the BIOS. All capacities listed in the above table are based
