You can configure a drive to become a master or slave by setting the master/slave jumpers. If only one jumper is installed or if neither jumper is installed, then the jumper settings on each drive determine whether that drive is a master or a slave. Alternatively, you can configure an ST9300 family drive as a master or slave using the cable select option. This requires a specialized daisy-chain cable that grounds pin 28 (CSEL) on one of its two drive connectors. If you attach the drive to the grounded CSEL connector, it becomes a master. If you attach the drive to the ungrounded CSEL connector, it becomes a slave. To use this option, the host system and both drives must support cable select. To configure an ST9300 family drive for cable select, install both master/slave jumpers. Regardless of which jumper settings are used, the slave drive must assert the DASP- signal at power up and the master drive must monitor DASP- at power up for the slave to be recognized. +---------+----------+-------------------------------------------+ | Jumper | Jumper | | | for pins| for pins | | | A and B | C and D | CONFIGURATION | +---------+----------+-------------------------------------------+ | OPEN | OPEN | Drive is master; slave drive may be | | | | detected using DASP- signal.

B, 09/1994 Notes On Installation ===================== Mounting the drive ------------------ You can mount ST9300 family drives in any orientation. Allow a mini- mum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.These drives conform to the industry- standard MCC direct-mounting specifications and require the use of MCC-compatible connectors in direct-mounting applications. NOTE The I/O connector pins may extend up to 0.010 inches beyond the edge of the head/disc assembly. CAUTION To avoid damaging the drive: - Use M3X0.5 metric mounting screws only. - Do not insert mounting screws more than 0.150 inches (3.81 mm) into the mounting holes. - Do not overtighten the screws (maximum torque: 3 inch-lb). Handling and static-discharge precautions ----------------------------------------- After unpacking, and before installation, the drive may be exposed to potential handling and ESD hazards. It is mandatory that you observe standard static-discharge precautions. A grounded wrist-strap is pre- ferred. Handle the drive only by the sides of the head/disc assembly. Avoid contact with the printed circuit board, all electronic components and the interface connector. Do not apply pressure to the top cover. Always rest the drive on a padded antistatic surface until you mount it in the host system. Attaching Cables ---------------- This drive is designed for a host computer that supplies interface signals and +5V power through a single 44-pin connector and cable. ATA interface ------------- The ST9300 family drives use the industry-standard ATA task file interface. The drives support both 8-bit and 16-bit data transfers. They support ATA programmed input/output (PIO) modes 0, 1 and 3, as well as ATA single-word DMA modes 0, 1 and 2, and ATA multiword DMA modes 0 and 1. The ST9300 family drives also support the use of the IORDY signal to provide reliable high-speed data transfers. The drives can differentiate between a hard reset and a soft reset while in Sleep mode. You can use a daisy-chain cable to connect two drives using the same AT host bus. Interface connector ------------------- The drive connector is a 44-conductor connector with 2 rows of 22 male pins on 0.079-inch (2 mm) centers (see Figure 4). The mating cable connector is a 44-conductor, nonshielded connector with 2 rows of 22 female contacts on 0.079-inch (2 mm) centers. The connectors should provide strain relief and should be keyed with a plug in place of pin 20. The ST9300 family drives are designed to support the industry- standard MCC direct-mounting specifications. When installing these drives in fixed mounting applications, use only MCC-compatible connectors such as Molex P/N 87368-442x. For applications involving flexible cables or printed circuit cables (PCCs), use Molex part number 87259-4413 or equivalent to connect the drive to the system. Select a connector that provides adequate clearance for the master/ slave configuration jumpers if the application requires the use of such jumpers. The ATA interface cable should be no more than 18 inches long.

B, 09/94 ECC testing ----------- When an ST9300 family drive performs hardware-based ECC error correction on-the-fly, the drive does not report an ECC error. This allows ECC correction without degrading drive performance. Some older drive diagnostic programs test ECC features by creating small data errors and then checking to see if they are reported. Such tests, when run on an ST9300 family drive, may incorrectly report an ECC detection failure because the drive hardware corrects the data automatically, avoiding the error rather than reporting it. Such a report does not indicate a drive malfunction. Power-management modes ---------------------- Power management is required for low-power and portable computer systems. In most systems, you can control power management through the system setup program. The ST9300 family drives feature several power-management modes, which are described briefly below: Active mode ----------- The drive is in Active mode during the read/write and seek operations. Idle mode --------- At power-on, the drive sets the idle timer to enter Idle mode after 5 seconds of inactivity. You can set the idle timer delay using the system setup utility. In Idle mode, the spindle remains up to speed. The heads are parked away from the data zones for maximum data safety. The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disc access is necessary. Standby mode ------------ The drive enters Standby mode when the host sends a Standby Immediate command. If the standby timer has been set by the host system, the drive can also enter Standby mode automatically after the drive has been inactive for a specifiable length of time. The standby timer delay is system-dependent and is usually established using the system setup utility. In Standby mode, the buffer remains enabled, the heads are parked and the spindle is at rest. The drive accepts all commands and returns to Active mode any time disc access is necessary. Sleep mode ---------- The drive enters Sleep mode after receiving a Sleep Immediate command from the host. The heads are parked and the spindle is at rest. The drive leaves Sleep mode when a Hard Reset or Soft Reset command is received from the host. After receiving a soft reset, the drive exits Sleep mode and enters Standby mode with all current emulation and translation parameters intact. Rest mode --------- Some host systems reduce drive power consumption by removing all power from the drive, using a state known as Rest mode. As the drive enters Rest mode, the host saves drive state information (including current logical geometry, set feature parameters, cache status and task file registers) before powering down the drive. After power is restored, the host restores the drive to its prerest condition. Rest mode is implemented using three commands: Rest, Read Drive State and Restore Drive State. The Rest command prepares the drive for a subsequent Read Drive State command. The Read Drive State com-mand captures the state of the I/O registers. The Restore Drive State command reads the drive state data from memory and restores the drive state based on this data. Idle and standby timers ----------------------- The drive sets the default time delay for the idle timer at power-on. In most systems, you can set this delay using the system setup utility. Each time the drive performs an Active function (read, write or seek), the idle and standby timers are reinitialized and begin counting down from their specified delay times to zero. If the idle timer reaches zero before any drive activity is required, the drive makes a transition to Idle mode. If the host has set the standby timer, the standby countdown continues. If the host has not set the standby timer, the drive remains in Idle mode. If the standby timer reaches zero before any drive 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. Deferred spinup --------------- ST9300 family drives may be factory-configured for deferred spinup. If configured for deferred spinup, the drive does not spin up immediately after power-on but waits until a command is received from the host. At power-on, the drive posts a status of 80H and all master/slave protocols are completed before the drive reports a status of 50H. After the drive receives a command from the host, it executes the normal spinup/upload process. If the host issues a soft reset before the drive spins up, the drive responds normally, except that it does not spin up until receiving a command from the host. Formatting and partitioning the drive ------------------------------------- CAUTION Formatting or partitioning a drive that contains data destroys that data. Make sure all data has been safely backed up before repartitioning or reformatting a drive. Seagate Technology assumes no liability for lost data. Low-level formatting -------------------- Seagate AT Interface drives are low-level formatted at the factory and do not require additional low-level formatting before use. Partitioning ------------ The partitioning process subdivides a single disc drive into partitions that behave as separate logical drives (labeled C, D, E, etc.). You can also set up the entire disc as a single partition. NOTE If you are using a version of DOS prior to Version 4.0, the operating system cannot access more than 32 Mbytes in a single partition. Therefore, you must divide a drive with a capacity of over 32 Mbytes into several smaller parti-tions. We do not recommend using ST9300 family drives with DOS versions prior to Version 3.3.
