• 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...
Power specifications The drive receives DC power (+5V or +12V) through a four-pin standard drive power connector. 2.8.1 Power consumption Power requirements for the drives are listed in the tables beginning on page 15. 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.

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.
activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the drive accepts all commands and returns to Active mode when disc access is necessary. 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.
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 63 G based on half-sine shock pulses of 2 msec.
2.10 Acoustics Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All mea- surements 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.
2.11 Electromagnetic immunity When properly installed in a representative host system, the drive operates without errors or degradation in performance when subjected to the radio frequency (RF) environments defined in the following table: Table 11: Radio frequency environments Performance Reference Test Description level...
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 DiamondMax 20 PATA Product Manual, Rev.
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.

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.
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 40 for details and sub- commands used in the S.M.A.R.T. implementation. Table 12: Supported ATA commands Command name...

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.
) that elimi- 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. to enable this feature. The table below shows the S.M.A.R.T. command codes that the drive uses.
