Medalist 1640 and 2140 Product Manual, January 1996 v

Introduction

This manual describes the functional, mechanical and interface specifi-

cationsfortheMedalist1640 and 2140 hard disc drives. The drives are

referred to throughout this manual by their model numbers, ST31640A

for the Medalist 1640 and ST32140A for the Medalist 2140.

The Seagate®ST31640A and ST32140A are high-capacity, Fast ATA-2

performance drives. The drives’ features include: 3 and 4 data-surfaces

respectively, 5,376-RPM spindle speed, embedded servo technology, a

16-bit internal microprocessor and an intelligent controller. These fea-

tures and others combine to give you high-performance, high-capacity

and energy-efficient drives.

Fast ATA-2 offers you the twin-performance advantage of larger data-

volume transferred at higher speeds. Fast ATA-2 assures you of PIO

mode 4 and multiword DMA mode 2 for burst transfer rates of up to 16.6

Mbytes per second. (The drives support all PIO and all multiword DMA

transfer modes. The transfer rate for any given operation depends on

capability of the entire system.1) Fast ATA-2 also means that Multiple

block read/write is supported. This feature allows multiple blocks of data

to be stored in cache and transferred in a single burst. These features

make the drives responsive to the demands of high-performance Pen-

tium and PowerPC-class microprocessors and VL and PCI Local Bus

architectures.

These 5,400-RPM class drives use embedded servo technology to

ensure quick and accurate access to information on the drive without

thermal recalibration interruptions. They use a 16-bit internal microproc-

essor that is more responsive to 32-bit operating systems and an

intelligent controller that provides data streaming----direct data transfers

between the host and the drive without microprocessor intervention.

These features increase the sustained data-transfer rate, facilitating

video playback and other multimedia operations. Coupled with the

1.62-Gbyte and 2.11-Gbyte capacities, the drives have more than

enough capacity to download and play back a complete CD-ROM.

The ST31640A and ST32140A are energy-efficient drives. They feature

the power modes defined in the ATA-2 standard. Standby and Sleep

modes reduce power consumption to a low 0.755 watts (typical). The

drivesenter power-saving modes at the request ofthe computer and can

be programmed to automatically enter Idle or Standby modes. (The ATA

commands with specific applications for the drives and the Seagate-

unique commands the drives use are discussed in Section 3.0 on page

25. A complete listing of the commands the drive supports is found in the

table on page 27. )
