Introduction
This manual describes the functional, mechanical and interface specifi-
cations for the Medalist® Pro 2520 and Medalist Pro 2160 hard disc
drives. The drives are referred to throughout this manual by their model
numbers, ST52520A for the Medalist Pro 2520 and ST52160A for the
Medalist Pro 2160.
Seagate®
desktopproductstakeastepintothefuturewiththeST52520A
and ST52160A. These drives feature MR heads and PRML recording
technology, Fast ATA-2 performance, segmented cache, embedded
servo technology, low noise, power management and S.M.A.R.T. capa-
bilities.
MR heads and PRML recording technology provide the drives with
increased areal density. This means that more data can be stored on a
single disc. Only two discs are used in the ST52520A and ST52160A
drives.
Fast ATA-2 performance means that the drives support PIO mode 4,
multiword DMA mode 2 transfer modes and multiple block read/write.
When the host chooses either transfer mode, the drives provide burst-
transfer rates of up to 16.6 Mbytes per second. The multiple block
read/write feature allows the drives to store several blocks of data in
cache and transfer them in a single burst.
These drives use a 128-Kbyte segmented cache. Segmenting the cache
providesadesignatedareawhereblocksofcontiguousreadorwritedata
can be staged for transfer in a single burst.
The ST52520A and ST52160A drives have other features that ensure
fast data throughput. Embedded servo technology allows the drives to
position the heads for data retrieval efficiently and accurately while
eliminating the periodic thermal recalibration that can interrupt during
data transfers. These drives also use a 16-bit microprocessor and an
intelligent controller that provides data streaming: direct data transfers
between the drive and the host without microprocessor intervention.
These features allow for a sustained data-transfer rate that facilitates
video playback and other multimedia operations.
These drives support Active, Idle and Standby power-management
modes. Power-saving modes can be controlled by the host computer.
Standby mode reduces power consumption to 1 watt (typical) while
retaining drive accessibility.
Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) is
available on these drives. Implementation of this feature is discussed on
page 35. To use the feature, you must have a BIOS, a software driver or
application software that supports S.M.A.R.T.

The ATA commands with specific applications for these drives and the
Seagate-unique commands the drives use are discussed in Section 3.0
onpage25.Acompletelistofthecommandsthedrivessupportarefound
