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®desktopproductstakeastepintothefuturewiththeST39140A,
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.Embeddedservotechnologyallowsthedrives topositionthe
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.
ThedrivessupportActive,IdleandStandbypower-managementmodes.
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
onpage25.Acompletelistofthecommandsthedrivessupportarefound

1.0 Specifications
1.1 Formatted Capacity
These drives support cylinder-head-sector (CHS) and logical-block ad-
dressing (LBA) translation modes. You can use the Identify drive (ECH)
command to verify the address modes the drives support, the number of
cylinders,sectorspertrack,totalnumberofsectors,headsandotherparame-
ters. The Identify drive parameters are listed in Section 3.2.1 on page 29.
Notes:
1. DOS and FAT 16 cannot access more than 2.147 Gbytes per parti-
tion. You must create multiple partitions to access the drive’s full ca-
pacity.
2. One Mbyte equals one million bytes.
3. If the system BIOS does not support more than 4,092 cylin-
ders, it may cause the computer to hang during startup, or it
may 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 accommo-
date more than 4,092 cylinders.

1.4 Physical dimensions
The mounting dimensions are shown in Figure 6 on page 23.
Height, max 1.027 inch (26.1 mm)
Width, max 4.010 inches (101.9 mm)
Depth, max 5.787 inches (146.1 mm)
Weight 1.5 lb (0.68 Kg)
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 single-track
seeks in both directions.
•Average seek time is measured by executing seeks in both directions
between random cylinders.
•Full-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 (typ) Average/typical seek time Full-stroke seek time (typ) Average latency
2.0 msec seek
2.5 msec read
3.5 msec write
9.5 msec read
10.5 msec write 21.0 msec seek 22.0 msec read
23.5 msec write
4.16 msec
Note. Host overhead varies between systems and cannot be specified.
Drive internal overhead is measured by issuing a no-motion seek.
Overhead is typically less than 0.5 msec.
1.6 Multisegmented cache buffer
The Medalist Pro ST39140A, ST36530A, and ST34520A drives are
available with a 512-Kbyte, multisegmented cache buffer that improves
performance by reducing access times.
Read look-ahead. The drive uses the read segments to store additional
logical sectors, after the last requested sector, into a buffer before the
computer requests the additional sectors. The cache buffer stores data
Medalist Pro 9140, 6530 and 4520 Product Manual, Rev. B 7

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 stop times
Within 20 seconds after power is applied, the drive is ready. Within 15
seconds after power is removed, the drive spindle stops rotating.
1.8 Typical power-up and power-down sequence
This section describes typical power-up and power-down sequences to
assist you in evaluating the drive’s performance. They are not perform-
ance specifications. A typical startup current profile is shown in Figure 1.
Startup current profiles are unique for each drive.

1.9 Power-up sequence
1. Power is applied to the drive.
2. The spindle motor reaches operating speed in about 4 seconds.
3. The airvane actuator-lock releases the actuator.
4. The drive synchronizes to servo pattern.
5. Calibration routines are performed.
5.6. The heads move back to track 0 and the drive is ready.
1.9.1 Power-down sequence
Caution. Do not move the drive until the motor has come to a complete
stop.
1. The power is turned off.
2. The read/write heads automatically move to the landing zone, which
is inside the maximum data cylinder.
3. The airvane actuator-lock mechanism locks the arm. This completes
the power-down sequence.
4. Within 15 seconds, the drive stops rotating.
1.10 Auto-park
During power-down, the read/write heads automatically move to the
landing zone. The heads park inside the maximum data cylinder and the
airvane actuator-lock engages. When power is applied, the heads recali-
brate to track 0.
1.11 Power specifications
1.11.1 Power management
ThedrivesupportsActive, IdleandStandbypower-managementmodes.
The power-management commands the drive supports are listed in the
table on page 27. Thetable on page11showstheaveragetypical power
consumption rates for each power-management mode. The test criteria
for each mode is defined on the following page. The Idle and Standby
timers are disabled at the factory.
Medalist Pro 9140, 6530 and 4520 Product Manual, Rev. B 9

All measurements were taken at the drive power connector. A true RMS
meter is used to measure all modes except Standby. A DMM is used for
Standby measurements.
1.11.1.1 Active mode
During the Active mode, the drive is involved in spinup, seeking or
read/write activities. The table on page 11 shows the typical power-con-
sumption rates for these activities.
•Spinup. The drive enters the Spinup mode from the Standby mode
and brings the spindle and discs up to operating speed. Power in this
mode is defined as the peak power after starting spinup.
•Seek. The drive enters the Seek mode from the Idle mode. The
read/write heads are moved to a specific location on the disc surface
in preparation for reading from or writing to the disc. Read/write
electronicsarepowereddownbutservoelectronicsareactive.Typical
power is defined as the power average of executing random seeks
with a 2-revolution (22.2 msec) dwell between Seek commands.
•Read/write. Read/write mode is entered from Idle mode. Read/write
electronics are activated and the servo is on track. The drive reads
from or writes to the disc.
1.11.1.2 Idle mode
The Idle mode is entered 1 minute after the last disc I/O activity. The
motor is up to speed and the actuator is repositioned once every minute.
The drive enters Idle mode from either Active or Standby mode, when
the host issues an Idle command only.
1.11.1.3 Standby mode
The spindle is stopped, the heads are parked in the landing zone, the
actuator is latched and some of the drive electronics are powered down.
Note. When recovering from Standby or Sleep mode, you must allow
the drive to post ready before reporting a timeout. The drive can
take up to 20 seconds to post ready. In a master and slave
configuration, the master can wait up to 31 seconds for the slave
to complete diagnostics before posting ready.
