B 1.7.2 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.
Barracuda ATA Family Product Manual, Rev. B 11 • Standby mode The drive enters Standby mode when the host sends a Standby Immediate command. If the host has set the standby timer, 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 established using a Standby or Idle command. In Standby mode, the drive buffer is enabled, the heads are parked and the spindle is at rest.

Barracuda ATA Family Product Manual, Rev. B 17 2.0 Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. 2.1 Handling and static-discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards.
18 Barracuda ATA Family Product Manual, Rev. B 2.2 Jumper settings 2.2.1 Master/slave configuration The options jumper block shown in Figure 2 is used to configure the drive for operation. It is the 6-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. Master or single drive. The drive is configured at the factory for a master or single-drive operation with a jumper set on pins 7 and 8. Drive as slave.
Barracuda ATA Family Product Manual, Rev. B 19 2.2.2 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 on pins 5 and 6 as shown in Figure 2 on page 18. Refer to your computer manual to determine whether your computer supports this option. 2.2.

Barracuda ATA Family Product Manual, Rev. B 21 3.0 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 0–4. 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.
