Maxtor 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-5 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.

Maxtor 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.

All Maxtor hard 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). Maxtor hard drives power-up in a translate mode:

Logical Block Addressing

The Logical Block Address (LBA) mode can only be utilized in systems that support this form of translation. The
cylinder, head and sector geometry of the drive, as presented to the host, differs from the actual physical
geometry. The host AT computer may access a drive of set parameters: number of cylinders, heads and sectors
per track, plus cylinder, head and sector addresses. However, the drive can’t use these host parameters directly
because of zoned recording techniques. The drive translates the host parameters to a set of logical internal
addresses for data access.

The host drive geometry parameters are mapped into an LBA based on this formula:

LBA

= (HSCA - 1) + HHDA x HSPT + HNHD x HSPT x HCYA

(1)

= (HSCA - 1) + HSPT x (HHDA + HNHD x HCYA)

(2)

where

HSCA = Host Sector Address, HHDA = Host Head Address
HCYA = Host Cylinder Address, HNHD = Host Number of Heads
HSPT = Host Sectors per Track
