Introduction

This manual describes the functional, mechanical and i nterfac e spec ifi ­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 technol ogy,
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 bloc ks 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 micr oprocessor intervention. These fea­tures allow for a sustained data-transfer rate that facilitates video play­back 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 applicati ons 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.

1.0 Specifications

1.1 Formatted Capacity

These drives support cylinder-head-sector (CHS) and logical -block ad­dressing (LBA) translation modes. You can use the Identify drive (EC
command to verify the address modes the drives support, the number of
cylinders, sectors per track, tota l number of sectors, head s and other parame­ters. 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 crea te mult iple p artitions to a ccess the drive’s f ull ca­pacity.

2.

One Mbyte equals one million bytes.

3.

If the system BIOS does not support more than 4,092 cylin­ders, 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 accommo­date more than 4,092 cylinders.

Width, max 4.010 inches (101.9 mm)

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 l east 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 s eek from track 0 to
the maximum track and back to track 0.

Track-to-track
seek time (typ)

2.0 msec seek

2.5 msec read

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.

computer requests the additional sectors. The cac he buffer st ores data

The drive uses the read segments to store additional

8 Medalist Pro 9140, 6530 and 4520 Product Manual, Rev. B

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 compl ete. 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 dr ive’s per formance. They are not perform ­ance specifications. A typical startup current profile is shown in Figure 1.

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.

1.

The power is turned off.

2.

The read/write heads automatically move to the landi ng zone, whi ch
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.

Do not move the drive until the motor has come to a complete
stop.

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 recali­brate to track 0.

1.11 Power specifications

1.11.1 Power management

The drive supports Active, Idle and Standby power-management modes.
The power-management commands the drive supports are listed in the
table on page 27. The table on page 11 shows the average typical 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.
