Introduction
This manual describes the functional, mechanical and interface specifications 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
®
desktop products take a step into the future with the ST52520A
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. capabilities.
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 P IO mode 4,
multiword DMA mode 2 transfer modes and multiple block read/write.
When the host chooses either transfer mode, the driv es provide burs ttransfer 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
provides a designated area where blocks of contiguous read or write data
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 t hat can interrupt during
data transfers. These drives also use a 16-bit microprocessor and an
intelligent controller t hat provides data streaming: direct data transfers
between the drive and the host without microprocessor intervention.
These features allow for a sus tained 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.
2 Medalist Pro 2520/2160 Product Manual, Rev. C
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.
The following is a summary of the drives’ features:

1.1 Formatted Capacity
Medalist Pro drives are low-level formatted at the factory. You cannot
low-level format them.
These drives suppo rt cylinder-he ad-sec tor (CHS) and log ical-bloc k addre ssing (LBA) translatio n modes . You can use the Ident ify drive (EC
to verify the address modes the drives support, the number of cylinders,
sectors per track, t ot al num ber of sectors, heads and other paramete rs . Th e

must create 2 or mo re partitions to access the drive’s full ca pacity.
One Mbyte equals one million bytes.
2.
. If the system BIOS does not support more than 4,096 cylin-
3
ders, it can cause the computer to hang during boot, or it can
truncate or wrap the cylinders. To resolve this issue the system BIOS needs to be modified: the cylinder register or variable must be increased from 12-bits to 16-bits to
accommodate more than 4,096 cylinders.

1.5 Seek time
Seek value is the interval between the time the actuator begins to move
and the time the head has settled over the target track. Seek time is a
true statistical average of at least 10,000 measurements of seek time.
All measurements are taken under nominal conditions of temperature
and voltage with the drive mounted horizontally. The specifications in the
table below are defined as follows:
• Track -to-track seek time is the average of all possible s ingle-track
seeks in both directions.
• Average seek time is measured by executing seeks in both directions
between random cylinders.
• Ful l-stroke seek time is half the time needed to seek from track 0 to
the maximum track and back to track 0.
Track-to-track
seek time

Host overhead varies between systems and cannot be specified.
Note.
Drive internal overhead is measured by issuing a no-motion seek.
Overhead is typically less than 0.5 msec.

from the start of a read until the buffer segment is full or until another
command is received.
Write immediate
. The drive uses the write segment to store write
commands and data. After the drive receives all of the data for the
command, it issues a write complete. Then, the drive writes the data to
the disc.
Write merging.
The drive accepts contiguous write commands and
executes them as one command.
1.7 Start and sto p times
Within 20 seconds after power is applied, the drive is ready. Within 15
seconds after power is removed, the drive spindle stops rotating.
