Introduction
This manual describes the functional, mechanical and interface specifications for the Medalist 630xe and the Medalist 850xe hard disc drives.
The drives are referred to throughout this manual by their model numbers, ST3630A for the Medalist 630xe and ST3850A for the Medalist
850xe.
The ST3630A and ST3850A are designed to meet the needs of entry
level-to-midrange desktop computers . They are standard 3.5-inch formfactor drives that feature advance transfer modes, Multiple block
read/write, segmented cache and power management. Their respective
631.1-Mbyte and 850.5-Mbyte capacities provide ample space to store
large software programs and for those programs to run efficiently.
Fast-A T A performanc e is available in both drives. The ST3850A supports
advanced PIO modes 3 and 4 and advanced multiword DMA modes 1
and 2 for burst transfer rates up t o 16.6 Mbytes per second. The ST3630A
supports advanced PIO mode 3 and advanced multiword DMA mode 1
for burst trans fer rates up to 13.3 Mbyt es per second. Both drives support
Multiple block read/write, which allows them to store contiguous blocks
of data in their 120-Mbyte segmented cache and to transfer the blocks
in a single burst.
The drives support power-management modes for energy-efficient operation. Power dissipation falls to 0.725 W (typical) in Standby mode.
The drives enter power-saving modes at the request of the host. They
can also be programmed to automatically enter power-saving modes
using the Idle timer or Standby timer commands. The power-management modes the drives support are discussed in subsection 1.7.1 on
page 8. The power-management commands the drives s upport are listed
in the ATA-command table on page 24.

1.0 Specification summary
1.1 Format configuration
The drive is low-level formatted at the factory. You do not need to
low-level format the drive.
You can operate the drive using many different address configurations,
provided the number of sectors per track does not exceed 63. The
following tables show the cylinder head sector (CHS) translation geometry for the drive. You can verify the parameters using the Identify Drive
(EC
) command.
