Medalist Pro Product Manual, Rev. D 1.0 1 Scope This manual describes the Seagate Technology®, Inc. Medalist Pro™ disc drives. Medalist Pro drives support the small computer system interface (SCSI) as described in the ANSI SCSI, SCSI2, and SCSI-3 (Fast-20 and Fast-40) interface specifications to the extent described in this manual. The SCSI Interface Product Manual (part number 77738479) describes general SCSI interface characteristics of this and other families of Seagate drives.

PAGE 13
Medalist Pro Product Manual, Rev. D 2.0 3 Applicable standards and reference documentation The drive has been developed as a system peripheral to the highest standards of design and construction. The drive depends upon its host equipment to provide adequate power and environment in order to achieve optimum performance and compliance with applicable industry and governmental regulations.

Medalist Pro Product Manual, Rev. D 3.0 5 General description Medalist Pro drives combine magnetoresistive (MR) heads, partial response/maximum likelihood (PRML) read channel electronics, embedded servo technology, and a SCSI-3 (Fast-20 and Fast-40) interface to provide high performance, high capacity data storage for a variety of systems including high-end desktop systems, workstations, and entry level servers.

6 Medalist Pro Product Manual, Rev. D Medalist Pro drives use a dedicated landing zone at the innermost radius of the media to eliminate the possibility of destroying or degrading data by landing in the data zone. The drive automatically goes to the landing zone when power is removed. An automatic shipping lock prevents potential damage to the heads and discs that results from movement during shipping and handling.

Medalist Pro Product Manual, Rev. D 11 Notes for Section 4.2. [1] Execution time is measured from receipt of the last Byte of the Command Descriptor Block (CDB) to the request for a Status Byte Transfer to the Initiator (excluding connect/disconnect). [2] Maximum times are specified over the worst case conditions of temperature, voltage margins and drive orientation. When comparing specified access times, care should be taken to distinguish between typical access times and maximum access times.

On a cache “hit” the drive ignores the “buffer-full” ratio rules.

14 5.1.4 Medalist Pro Product Manual, Rev. D Seek errors A seek error is defined as a failure of the drive to position the heads to the addressed track. There shall be no more than one recoverable seek errors in 10 7 physical seek operations. After detecting an initial seek error, the drive automatically reseeks to the addressed track up to 3 times.

Medalist Pro Product Manual, Rev. D 5.2.6 15 Hot plugging Medalist Pro disc drives The ANSI SPI-2 (T10/1142D) document defines the physical requirements for removal and insertion of SCSI devices on the SCSI bus. Four cases are addressed. The cases are differentiated by the state of the SCSI bus when the removal or insertion occurs.
PAGE 26
16 Medalist Pro Product Manual, Rev. D You can interrogate the drive through the host to determine the time remaining before the next scheduled measurement and data logging process occurs. To accomplish this, issue a Log Sense command to log page 0x3E. This allows you to control when S.M.A.R.T. interruptions occur. Forcing S.M.A.R.T. with the RTZ command resets the timer. Performance impact S.M.A.R.T. attribute data is saved to the disc so that the events that caused a predictive failure can be recreated.

Medalist Pro Product Manual, Rev. D 17 Product repair and return information Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does not sanction any third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids the warranty (see Section 10.0).

Medalist Pro Product Manual, Rev. D 7.0 31 Defect and error management The drive, as delivered, complies with this specification. The read error rate and specified storage capacity are not dependent upon use of defect management routines by the host (initiator). Defect and error management in the SCSI system involves the drive internal defect/error management and SCSI systems error considerations (errors in communications between Initiator and the drive).

Medalist Pro Product Manual, Rev. D 8.0 33 Installation The first thing to do when installing a drive is to set the drive ID (select) on the SCSI bus and set up certain operating options. This is usually done by installing small shorting jumpers on the pins of connector J2 on the PCB (or J1-Auxiliary on the “W” and “LW” models), or via the drive to host I/O signals on “WC” and “LC” models. Some users connect cables to J6 or J1-Auxiliary and perform the set-up using remote switches.

Medalist Pro Product Manual, Rev. D 9.3.2 49 Mode Sense data The Mode Sense command provides a means for the drive to report its operating parameters to the initiator. The drive maintains four sets of Mode parameters, Default values, Saved values, Current values and Changeable values. Default values are hard coded in the drive firmware that is stored in flash EPROM nonvolatile memory on the drive PCB. Default values can be changed only by downloading a complete set of new firmware into the flash EPROM.

PAGE 69
Medalist Pro Product Manual, Rev. D 59 To minimize discontinuances and signal reflections, cables of different impedances should not be used in the same bus. Implementations may require trade-offs in shielding effectiveness, cable length, number of loads and spacing, transfer rates, and cost to achieve satisfactory system operation. If shielded and unshielded cables are mixed within the same SCSI bus, the effect of impedance mismatch must be carefully considered.

The conductor number refers to the conductor position when using 0.025-inches (0.635 mm) centerline flat ribbon cable. Other cables types may be used to implement equivalent contact assignments. Connector contacts are on 0.050 inches (1.27 mm) centers.

See Section 8.1 for illustrations that show how to place jumpers enabling each of the following terminator power configurations: 1. Drive accepts terminator power through SCSI bus pins: “N” models Pin 26 “W” models Pins 17, 18, 51, and 52 2. Drive supplies power to the SCSI bus. 3.
