2.6 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. • Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead. *Typical seek times (msec) Read Write Track-to-track <0.8 <1.
• Idle mode power Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track location. • Standby mode During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/ write electronics are in power-down mode. Table 4: DC power requirements Power dissipation (4-Disc values shown) Average (watts, 25° C) Average 5V typ amps Average 12V typ amps Spinup — — 2.90 (peak) Idle* 9.30 0.611 0.
2.8.1.1 Typical current profile Figure 1 Typical 5V startup and operation current profile Figure 2 Typical 12V startup and operation current profile 2.8.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 volt line or an equivalent 15-ohm resistive load on the +5 volt line. • Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave injected noise at up to 10 MHz.
2.8.3 Voltage tolerance Voltage tolerance (including noise): 5V ± 5% 12V ± 10% 2.8.4 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.
2.9 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. Recommended measurement locations are shown in See Figure 6 on page 27. 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. Shocks should not be repeated more than two times per second. 2.9.5.
2.10 Acoustics Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are consistent with ISO document 7779. Sound power measurements are taken under essentially free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward. Note. For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined by the following equation: (Number of seeks per second = 0.

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. 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 36 for details and subcommands used in the S.M.A.R.T. implementation.
Command name Command code (in hex) Security Erase Unit F4H Security Freeze F5H Security Set Password F1H Security Unlock F2H Seek 70H Set Features EFH Set Max Address F9H Note: Individual Set Max Address commands are identified by the value placed in the Set Max Features register as defined to the right. Address: Password: Lock: Unlock: Freeze Lock: Set Max Address Extended 37H Set Multiple Mode C6H Sleep 99H or E6H S.M.A.R.T. Disable Operations B0H / D9H 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 is organized as a single 512-byte block of data, whose contents are shown in the Table 7 on page 30. 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 60–61 Total number of user-addressable LBA sectors available (see Section 2.2 for related information) *Note: The maximum value allowed in this field is: 0FFFFFFFh (268,435,455 sectors, 137 Gbytes). Drives with capacities over 137 Gbytes will have 0FFFFFFFh in this field and the actual number of useraddressable LBAs specified in words 100-103. This is required for drives that support the 48-bit addressing feature.
Word Description Value 104–127 ATA-reserved 0000H 128 Security status 0001H 129–159 Seagate-reserved xxxxH 160–254 ATA-reserved 0000H 255 Integrity word xxA5H 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) 34 Bit Word 63 0 Multiword DMA mode 0 is supported. 1 Multiword DMA mode 1 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 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.
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 monitors 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. predictability is limited to the attributes the drive can monitor. For more information on S.M.A.R.T.
