Introduction
This manual describes the functional, mechanical and interface specifi-
cations for the Medalist
®
Pro 9140, the Medalist Pro 6530 and the
Medalist Pro 4520 hard disc drives. The drives are referred to throughout
this manual by their model numbers, ST39140A for the Medalist Pro
9140, ST36530A for the Medalist Pro 6530, and ST34520A for the
Medalist Pro 4520.
Seagate
®
desktop products take a step into the future with the ST39140A,
ST36530A and ST34520A. These drives feature MR heads and EPRML
recording technology, Ultra ATA performance, 7,200-RPM technology,
segmented cache, embedded servo technology, low noise and power
management.
Ultra ATA performance means that the drive supports PIO mode 4,
multiword DMA mode 2 transfer modes and synchronous DMA mode.
When the host chooses Ultra DMA mode 2, the drive provides burst
transfer rates of up to 33.3 Mbytes per second. The multiple block
read/write feature allows the drive to store several blocks of data in its
512-Kbyte segmented cache and transfer the blocks in a single burst.
The Medalist Pro 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 data transfers. An intel-
ligent controller provides data streaming: direct data transfers between
the drive and the host without microprocessor intervention. These fea-
tures allow for a sustained data-transfer rate that facilitates video play-
back and other multimedia operations.
The 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 3.0 watts (typical) while retaining
drive accessibility.
Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) is
available on these drives. 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
on page 25. A complete list of the commands the drives support are found
in the table on page 27.
