Introduction This manual describes the functional, mechanical and interface specifications for the following Seagate DB35.4 Series model drive: ® ST3250310CS These drives provide the following key features: • Low profile deck design for improved air-flow and low-profile system design. • High instantaneous (burst) data-transfer rates (up to 300 Mbytes per second). -
Page 8: About The Serial Ata Interface
About the Serial ATA interface The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include: • Easy installation and configuration with true plug-and-play connectivity. It is not necessary to set any jump- ers or other configuration options. •... -

Page 14: Power Specifications
Power specifications The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 4 on page 18. 2.8.1 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, using 5.0V and 12.0V input voltage at 25°C ambient temperature. -

Page 17: Environmental Specifications
Environmental specifications 2.9.1 Drive case temperature Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters). Drive case temperature should be measured at the location indicated in Figure 5 on page 19. Operating (Drive case temperature) Nonoperating (Ambient *) * Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. -
Page 18: Vibration
2.9.6 Vibration All vibration specifications assume that the drive is mounted securely with the input vibration applied at the drive mounting screws. Vibration may be applied in the X, Y or Z axis. 2.9.6.1 Operating vibration The maximum vibration levels that the drive may experience while meeting the performance standards speci- fied in this document are specified below 5–22 Hz 0.25 Gs (Limited displacement) -
Page 19: Acoustics Emissions
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. -
Page 20: Reliability
EN 55024. 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. -
Page 21: Fcc Verification
Seagate 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, pursu- ant to Subpart J, Part 15 of the FCC rules. -
Page 22: Environmental Protection
The silver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chlo- ride, 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%. -
Page 23: Configuring And Mounting The Drive
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: •... -
Page 24: Configuring The Drive
Configuring the drive Each drive on the Serial ATA interface connects point-to-point with the Serial ATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationship. 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”... -
Page 25: Drive Mounting
Drive mounting You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 5 for drive mounting dimensions.

Page 35: Set Features Command
4.3.2 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. -
