To determine the warranty for a specific drive, use a web browser to access the following web page: http://www.seagate.com/www/en-us/support/warranty_&_returns_assistance From this page, click on the “Verify Your Warranty” link. You will be asked to provide the drive serial number, model number (or part number) and country of purchase. The system will dis- play the warranty information for your drive.
Formatted capacity Model ST9750423AS, ST9750423ASG, ST9750422AS, ST9750420AS and ST9750420ASG ST9640424AS, ST9640423AS and ST9640423ASG ST9500424AS, ST9500423AS and ST9500423ASG *One Gbyte equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting. 3.2.1 LBA mode When addressing these drives in LBA mode, all blocks (sectors) are consecutively numbered from 0 to n–1, where n is the number of guaranteed sectors as defined above.
Seek time Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows: • Track-to-track seek time is an average of all possible single-track seeks in both directions. •...
Power specifications The drive receives DC power (+5V) through a native SATA power connector. 3.9.1 Power consumption Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on an average of drives tested, under nominal conditions, at 25°C ambient temperature. •...

3.9.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on the +5V line. Using 5V power, the drive is expected to operate with a maximum of 100mV peak-to-peak square-wave injected noise at up to 10 MHz.
3.9.4 Power-management modes The drive provides programmable power management to provide greater energy efficiency. In most systems, you can control power management through the system setup program. The drive features the following power-management modes: Table 4: Power management modes Power modes Heads Active (operating) Tracking...
3.10 Environmental specifications This section provides the temperature, humidity, shock, and vibration specifications for Momentus drives. 3.10.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Above 1000 feet (305 meters), the maximum temperature is derated linearly by 1°C every 1000 feet. Operating: 0°C to 60°C (32°F to 140°F) Nonoperating:...
3.10.6 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. Note. Additional shock protection is provided by the Free Fall Protection feature on ST9750423ASG, ST9750420ASG, ST9640423ASG and ST9500423ASG models.
Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this pro- cess is the use of the absolute threshold of hearing. Seagate uses the lower limit for the threshold curve* to discern tone audibility and to compensate for the inaudible components of sound prior to computation of tone ratios according to Annex D of the ECMA-74 standards.
Information Technology Equipment (ITE). Emission levels are defined by EN 55022, Class B and the immunity levels are defined by EN 55024. Seagate uses an independent laboratory to confirm compliance with the EC directives specified in the previous paragraph. Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with the directives when used in the test systems, we cannot guarantee that all systems will comply with the directives.
As a subassembly, no Federal Communications Commission verification or certification of the device is required. Seagate Technology LLC has tested this device in enclosures as described above to ensure that the total assembly (enclosure, disc drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursuant to Subpart J, Part 15 of the FCC rules.
The sil- ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%.
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: •...
Configuring the drive Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationships. If two drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters”...
Drive mounting You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 5 for drive mounting dimensions. Follow these important mounting precautions when mount- ing the drive: • Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling. •...
Serial ATA (SATA) interface These drives use the industry-standard Serial ATA interface that supports FIS data transfers. It supports ATA programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–6. The drive also supports the use of the IORDY signal to provide reliable high-speed data transfers. For detailed information about the Serial ATA interface, refer to the “Serial ATA: High Speed Serialized AT Attachment”...

Table 7: Serial ATA connector pin definitions Segment Function Definition Ground 2nd mate Differential signal pair A from Phy Ground 2nd mate Differential signal pair B from Phy Signal...
Supported ATA commands The following table lists Serial ATA standard commands that the drive supports. For a detailed description of the ATA commands, refer to the Serial ATA: High Speed Serialized AT Attachment specification. See “S.M.A.R.T. commands” on page 31.for details and subcommands used in the S.M.A.R.T. implementation. Command name ATA-standard commands Device Configuration Restore...

5.3.2 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.
SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4 nates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at: http://seatools.seagate.com. This drive is shipped with S.M.A.R.T. features disabled. You must have a recent BIOS or software package that supports S.M.A.R.T.
