2.9 Power specifications The drive receives DC power (+5V) through the interface connector. 2.9.1 Power consumption Power requirements for the drives are listed in the table on page 11. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V input voltage at 25°C ambient temperature. • Spinup power Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.
2.9.1.1 Typical current profile Figure 1. Typical 5V startup and operation current profile 2.9.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on the +5 volt line. Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave injected noise at up to 10 MHz. Note. 2.9.3 Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.
2.9.4 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.
2.10 Environmental specifications 2.10.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature, measured on baseplate, should not exceed 90°C (194°F) within the operating ambient conditions. Operating Nonoperating 2.10.

Shock may be applied in the X, Y or Z axis. 2.11.1.
2.11.2 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. 2.11.2.1 Operating vibration The following table lists the maximum vibration levels that the drive may experience while meeting the performance standards specified in this document. 10–200 Hz 2.0 G (0 to peak) 200–500 Hz 1.0 G (0 to peak) 2.11.2.

2.15 Agency certification 2.15.1 Safety certification The drives are recognized in accordance with UL 1950 and CSA C22.2 (950) and meet all applicable sections of IEC950 and EN 60950 as tested by TUV North America. 2.15.2 Electromagnetic compatibility Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Electromagnetic Compatibility Directive (89/336/EEC).
Radio and television interference. This equipment generates and uses radio frequency energy and if not installed and used in strict accordance with the manufacturer’s instructions, may cause interference to radio and television reception. This equipment is designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives. 20 EE25 Series Product Manual, Rev.
3.0 Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. 3.1 Handling and static discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards.
3.2.2 Cable-select option Computers that use cable select determine the master and slave drives by selecting or deselecting pin 28, CSEL, on the interface bus. Master and slave drives are determined by their physical position on the cable. To enable cable select, set a jumper as shown in Figure 3. Refer to your computer manual to determine whether your computer supports this option. 3.
4.0 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. For detailed information about the ATA interface, refer to the AT Attachment - 6 with Packet Interface (ATA/ ATAPI-6), ANSI NCITS 361-200, subsequently referred to as the ATA-6 Standard.
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 ATA-6 Standard.
Command name Note: Individual Set Max commands are identified by the value placed in the Set Max Features register as defined to the right. Command code (in hex) Address Password Lock Unlock Freeze Lock Set Multiple Mode C6H Sleep 99H, E6H S.M.A.R.T.
4.1.2 Identify Device command The Identify Device command (command code ECH) transfers information about the drive to the host following power up. The data, shown below, is organized as a single 512-byte block of data. All reserved bits or words should be set to zero. Parameters listed with an “x” are drive-specific or vary with the state of the drive. See Section 2.0 on page 3 for default parameter settings.
Word Description Value 57–58 Current capacity in sectors xxxxH 59 Number of sectors transferred during a Read Multiple or Write Multiple command xxxxH 60–61 Total number of user-addressable LBA sectors available (see Section 2.
Word Description Value 129–159 Seagate-reserved xxxxH 160–254 ATA-reserved 0000H 255 Integrity word xxA5H Note. See the bit descriptions below for words 63, 88, 93 and 94 of the Identify Drive data. Description (if bit is set to 1) 28 Bit Word 63 0 Multiword DMA mode 0 is supported. 1 Multiword DMA mode 1 is supported. 2 Multiword DMA mode 2 is supported. 8 Multiword DMA mode 0 is currently active. 9 Multiword DMA mode 1 is currently active.
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 interrupt. 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.
