ST9190 Family Product Manual, Rev. B 5 1.10.6 Shock All shock specifications assume that the drive is mounted in an approved orientation with the input levels at the drive mounting screws. The nonoperating specifications assume that the read/write heads are positioned in the shipping zone. Note. At power-down, the read/write heads automatically move to the shipping zone. The head and slider assembly park inside of the maximum data cylinder. When power is applied, the heads recalibrate to Track 0. 1.10.6.

B 1.10.7.2 Nonoperating vibration The following table lists the maximum nonoperating vibration that ST9190 family drives may experience without incurring physical damage or degradation in performance when the drive is put into operation. 5–22 Hz 0.162-inch displacement (double amplitude) 22–450 Hz 4 Gs acceleration (peak) 450–22 Hz 4 Gs acceleration (peak) 22–5 Hz 0.162-inch displacement (double amplitude) 1.
ST9190 Family Product Manual, Rev. B 7 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. 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.
8 ST9190 Family Product Manual, Rev. B 1.11.2 Power consumption Power requirements for the ST9190 family drives are listed in the table below. Typical power measurements are based on an average of drives tested under nominal conditions, using 5.0V input voltage at 25°C ambient temperature at sea level. Active mode current and power are measured with two spindle rotations between each operation and the drive in default logical geometry.
ST9190 Family Product Manual, Rev. B 9 1.11.3 Conducted Noise The drive will operate with a maximum permitted conducted noise of: • 150 mV peak-to-peak triangular wave injected noise at the power connector. The frequency is 10 Hz to 100 KHz with equivalent resistive loads. • 100 mV peak-to-peak triangular wave injected noise at the power connector. The frequency is 100 KHz to 10 MHz with equivalent resistive loads. Note.
10 ST9190 Family Product Manual, Rev. B This equipment is designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television, which can be determined by turning the equipment on and off, you are encouraged to try one or more of the following corrective measures: • Reorient the receiving antenna.
ST9190 Family Product Manual, Rev. B 11 2.0 Drive mounting and configuration 2.1 Handling and static-discharge precautions After unpacking, and prior to installation, the drive may be exposed to potential handling and ESD hazards. Observe standard static-discharge precautions. A grounded wrist-strap is preferred. 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.

ST9190 Family Product Manual, Rev. B 13 2.3 Master/slave configuration A master/slave relationship must be established between multiple drives attached to a single AT bus. You can configure a drive to become a master or slave by setting the master/slave jumpers as described below and shown in Figure 3 on page 14. 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.
14 ST9190 Family Product Manual, Rev. B Master/slave configuration jumpers Pin 1 B A Pin 20 removed for keying Circuit board D C Drive is master; slave may be detected using DASP– signal Drive is master; Seagate slave drive present Drive is slave; Seagate master drive present Use CSEL pin grounding to differentiate master from slave Figure 3.
ST9190 Family Product Manual, Rev. B 15 2.4 Remote LED The drive indicates activity to the host through the DASP– line (pin 39) on the ATA interface. This line may be connected to a drive status indicator driving an LED at 5V. The line has a 30 mA nominal current limit. Note. If the drive is configured to use the DASP– signal to determine master/slave configuration, this signal is shared with the LED. In this configuration, DASP– signals will be visible as LED flashes. 2.
ST9190 Family Product Manual, Rev. B 17 3.0 ATA interface The ST9190 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 and 1, but do not support DMA data transfers. The drives can differentiate between a hard reset and a soft reset while in Sleep mode. You can connect up to two drives on the same AT host bus.
18 ST9190 Family Product Manual, Rev. B 3.2 ATA interface signals and connector pins The following diagram summarizes the signals on the ATA interface connector that are supported by the ST9190 family drives. For a detailed description of these signals, refer to the Seagate ATA Interface Reference Manual.
ST9190 Family Product Manual, Rev. B 3.2.1 19 AT bus signal levels Signals that the drive sends have the following output characteristics at the drive connector: Logic low 0.0V to 0.4V Logic high 2.5V to 5.25V Signals that the drive receives must have the following input characteristics, measured at the drive connector: Logic low 0.0V to 0.8V Logic high 2.0V to 5.
20 ST9190 Family Product Manual, Rev. B 3.3 ATA interface commands The following table lists ATA-standard and Seagate-specific drive commands that are supported by the ST9190 family drives. For a detailed description of these commands, refer to the Seagate ATA Interface Reference Manual.
ST9190 Family Product Manual, Rev.
22 ST9190 Family Product Manual, Rev. B The following commands are specific to the ST9190 family drives or contain drive-specific features. 3.3.1 Identify Drive command The Identify Drive command (command code ECH) transfers information about the drive to the host after power up. The data is organized as a single 512-byte block of data, whose contents are shown in the table below. All reserved bits or words should be set to zero.
ST9190 Family Product Manual, Rev. B Word 22 Description Number of ECC bytes available (16) Firmware revision (8 ASCII 23–26 character string): xx = ROM version, ss.tt = RAM version 27–46 23 ST9190AG ST9140AG 0010H 0010H xx.ss.tt xx.ss.
24 ST9190 Family Product Manual, Rev.
ST9190 Family Product Manual, Rev. B 3.3.2 25 Set Features command This command controls the implementation of various features supported by the drive. 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 supported by the drive, the command is aborted. Power-on default has the read look-ahead and write caching features enabled and 4 bytes of ECC.
