In most systems, you can control power management through the system setup program. The drive features the following power-management modes: Power mode Heads...
Environmental specifications 2.9.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 69°C (156°F) within the operating ambient conditions. Rec- ommended measurement locations are shown in See Figure 6 on page 29. Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters).
2.9.5 Shock All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis. 2.9.5.1 Operating shock These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 68 Gs based on half-sine shock pulses of 2 msec.

Korean RRL If these drives have the Korea Ministry of Information and Communication (MIC) logo, they comply with para- graph 1 of Article 11 of the Electromagnetic Compatibility control Regulation and meet the Electromagnetic Compatibility (EMC) Framework requirements of the Radio Research Laboratory (RRL) Ministry of Information and Communication Republic of Korea.
2.14.1 European Union Restriction of Hazardous Substances (RoHS) The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical substances, including Lead (Pb), in electronic products effective July 2006. Although amendments to the Euro-pean Union’s Restriction of Hazardous Substances (RoHS) Directive have not been finalized, to the best of our knowledge the disc drives documented in this publication will comply with the final RoHS Directive requirements.
Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. Handling and static discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic dis- charge (ESD) hazards. Observe the following standard handling and static-discharge precautions: Caution: •...
Breather filter hole precautions This section contains information regarding the precautions which should be taken regarding the breather filter hole in Seagate hard disc drives. Proper precautions should be taken to ensure full functionality and prevent possible damage to the drive. Breather hole Do not cover or seal this hole.
Jumper settings 3.3.1 Master/slave configuration The options jumper block shown in Figure 4 is used to configure the drive for operation. It is the 8-pin dual header between the interface connector and the power connector. Use the following settings to configure the drive as a master or a slave.
3.3.3 Ultra ATA/100 cable An 80-conductor 40-pin cable is required to run Ultra DMA mode 3, mode 4, and mode 5. This cable uses even-numbered conductors connected to the ground pins to improve signal integrity. Note. If you are using a 40-pin, 80-conductor cable, attach the blue connector to the motherboard, the black connector to the Master...
ATA interface These drives use the industry-standard ATA task file interface that supports 16-bit data transfers. It supports ATA programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–5. The drive also supports the use of the IORDY signal to provide reliable high-speed data transfers. You can use a daisy-chain cable to connect two drives to a single AT host bus.
4.1.1 Supported ATA commands The following table lists ATA-standard commands that the drive supports. For a detailed description of the ATA commands, refer to the Draft ATA-7 Standard. See “S.M.A.R.T. commands” on page 38 for details and sub- commands used in the S.M.A.R.T. implementation. Table 8: Supported ATA commands Command name...

Word Description Value Integrity word xxA5 Note. Advanced Power Management (APM) and Automatic Acoustic Management (AAM) features are not supported Note. See the bit descriptions below for words 63, 88, and 93 of the Identify Drive data: Description (if bit is set to 1) Word 63 Multiword DMA mode 0 is supported.
4.1.3 Set Features command This command controls the implementation of various features that the drive supports. When the drive receives this command, it sets BSY, checks the contents of the Features register, clears BSY and generates an inter- rupt. If the value in the register does not represent a feature that the drive supports, the command is aborted. Power-on default has the read look-ahead and write caching features enabled.
4.1.4 S.M.A.R.T. commands S.M.A.R.T. provides near-term failure prediction for disc drives. When S.M.A.R.T. is enabled, the drive moni- tors predetermined drive attributes that are susceptible to degradation over time. If self-monitoring determines that a failure is likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable. S.M.A.R.T.
