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

This mode is implemented per ANSI ATA/ATAPI-6 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.
/WNVK YQTF &/# /QFG
Supports multi-word Direct Memory Access (DMA) mode transfers.

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:
