2.0 Drive specifications Unless otherwise noted, all specifications are measured under ambient conditions, at 25°C, and nominal power. For convenience, the phrases the drive and this drive are used throughout this manual to indicate ST94011A, ST92011A, ST92811A, and ST94811A model drives. 2.1 Specification summary The specifications listed in this table are for quick reference. For details on specification measurement or definition, see the appropriate section of this manual.

2.7 Seek time Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications 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 1.5 2.0 Average 12.0 14.
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 8. 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.

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.
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 should not exceed 60°C (140°F) within the operating ambient conditions. Above 1,000 feet (305 meters), the maximum temperature is derated linearly by 1°C every 1000 feet. Operating Nonoperating 2.10.
2.10.5 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. 2.10.5.1 Operating shock These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 225 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second. 2.10.5.
2.11 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.
2.13 Reliability Measurement type Specification Nonrecoverable read errors 1 per 1014 bits read, max. Mean time between failures 330,000 power-on hours At nominal power, 25°C ambient temperature. Max case temperature: 60°C at the case measurement location shown in Figure 4.
Korean RRL If these drives have the Korea Ministry of Information and Communication (MIC) logo, they comply with paragraph 1 of Article 11 of the Electromagnetic Compatibility control Regulation and meet the Electromagnetic Compatibility (EMC) Framework requirements of the Radio Research Laboratory (RRL) Ministry of Information and Communication Republic of Korea. These drives have been tested and comply with the Electromagnetic Interference/Electromagnetic Susceptibility (EMI/EMS) for Class B products.
If necessary, you should consult your dealer or an experienced radio/television technician for additional suggestions. You may find helpful the following booklet prepared by the Federal Communications Commission: How to Identify and Resolve Radio-Television Interference Problems. This booklet is available from the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402. Refer to publication number 004-000-00345-4. 16 Momentus 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.
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-6 Standard. See “S.M.A.R.T. commands” on page 27. for details and subcommands used in the S.M.A.R.T. implementation.

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 on page 27. 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 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.
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) 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. 10 Multiword DMA mode 2 is currently active. Bit Word 88 0 Ultra DMA mode 0 is supported. 1 Ultra 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.
