∙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. Equivalent resistance (9.26 ohms) is calculated by dividing the nominal voltage (5V) by the typical RMS read/write current (0.54 amps).

Voltage tolerance (including noise): +5 volts, ± 5%

1.7.5Power-management modes

Seagate’s Marathon drives provide programmable power management to enhance battery life and to provide greater energy efficiency. In most computers, you can control power management through the system setup program. These drives feature several power-management modes, which are summarized in the following table and are described in more detail 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. The drive remains in Idle mode with heads flying over the media for 15 minutes; then the drive makes the transition to Active mode and seeks to the last-known logical block address, where it remains for 5 minutes. The drive then seeks to a new, unspecified location two more times, for 5 minutes each, after which it makes the transition to Standby mode. In Idle mode, the spindle remains up to speed, the buffer remains enabled, and the drive accepts all commands and returns to Active mode whenever a disc access command is re- ceived.

The drive enters Idle mode when an Idle or Idle Immediate command is received. The Idle or Idle Immediate command overrides the algorithm described above. The drive remains in Idle mode until a disc access command is received or the standby timer expires, whichever occurs first.
