Introduction
This manual describes the functional, mechanical and interface specifications 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 intelligent controller provides data streaming: direct data transfers between the drive and the host without microprocessor 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 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.

1.0Specifications
1.1Formatted Capacity
These drives support cylinder-head-sector (CHS) and logical-block addressing (LBA) translation modes. You can use the Identify drive (ECH) command to verify the address modes the drives support, the number of cylinders, sectors per track, total number of sectors, heads 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 partition. You must create multiple partitions to access the drive’s full 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.

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.

|
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
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 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 performance specifications. A typical startup current profile is shown in Figure 1. Startup current profiles are unique for each drive.
