Drive Specification ST33240A ST32531A Guaranteed Mbytes ( × 10 6 bytes) 3,227 2,557 Guaranteed sectors 6,303,...

1.0 Drive specifications Unless otherwise noted, all specifications are measured under ambientconditions, at 25°C, and nominal power. For convenience the phrasesthe drive and this drive are used throughout this manual to indicate boththe ST33240A and the ST32531A. 1.1 Formatted capacity ST33240A ST3...

1.5 Seek time All seek times are measured using a 486 AT computer (or faster) with an8.3 MHz I/O bus. The measurements are taken with nominal power atsea level and 25°C ambient temperature. All times are measured usingdrive diagnostics. The specifications in the table below are defined asfollows: • ...

1.7 Power specifications The drive receives DC power (+5V or +12V) through a four-pin standarddrive power connector. 1.7.1 Power consumption Power requirements for the drive are listed in the table below. Typical powermeasurements are based on an average of drives tested under nominalconditions, usi...

1.7.1.1 Typical current profile Figure 1 shows a typical current profile for the Medalist 3240 and theMedalist 2531. 1.7.2 Conducted noise Input noise ripple is measured at the host system power supply acrossan equivalent 80-ohm resistive load on the +12 volt line or an equivalent15 ohm resistive lo...

1.7.4 Power-management modes This drive provides programmable power management to providegreater energy efficiency. In most systems, you can control powermanagement through the system setup program. This Seagate drivefeatures several power-management modes, which are summarized inthe following table...

1.8.6.2 Nonoperating vibration The following table lists the maximum nonoperating vibration that thedrive may experience without incurring physical damage or degradationin performance when subsequently put into operation. 5–22 Hz 0.081-inch displacement (peak to peak) 22–350 Hz 5 Gs acceleration (ze...

Contact start-stop cycles 40,000 cycles(at nominal voltage and temperature,with 60 cycles per hour and a 50%duty cycle) Preventive maintenance None required 1.12 Agency certification 1.12.1 Safety certification The drive is recognized in accordance with UL 1950 and CSA C22.2(950) and meets all appli...

2.0 Drive mounting and configuration 2.1 Handling and static-discharge precautions After unpacking, and before installation, the drive may be exposed topotential handling and electrostatic discharge (ESD) hazards. You mustobserve standard static-discharge precautions. A grounded wrist-strap isprefer...

2.3 Drive mounting You can mount the drive in any orientation using four screws in theside-mounting holes or four screws in the bottom-mounting holes. SeeFigure 3 on page 19 for drive mounting dimensions. • Allow a minimum clearance of 0.030 inches (0.76 mm) around theentire perimeter of the drive f...

3.0 ATA interface This drive uses the industry-standard ATA task file interface. It supportsboth 8-bit and 16-bit data transfers. It supports ATA programmed in-put/output (PIO) modes 0, 1, 2, 3 and 4; ATA single-word DMA modes0, 1 and 2; and ATA multiword DMA modes 0, 1 and 2. The drive alsosupports...

The following commands contain drive-specific features that may not bedescribed in the Draft Proposed ATA-3 Standard. 3.2.2 Identify Drive command The Identify Drive command (command code EC H ) transfers information about the drive to the host following power up. The data is organized asa single 51...

3.2.3 Set Features command This command controls the implementation of various features that thedrive supports. When the drive receives this command, it sets BSY,checks the contents of the Features register, clears BSY and generatesan interrupt. If the value in the register does not represent a feat...
