•Active mode

The drive is in Active mode during the read/write and seek operations.

•Low power idle mode

Drive enters Low Power Idle mode from Performance Idle mode when the Advanced Power Management Level is set between FDh and 80h, and the Idle timer is reached at 2 seconds (default setting is 2 seconds). Disc is not spinning and heads are parked and drive accepts all commands and returns to Active mode any time disc access is necessary.

•Performance idle mode

The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disc access is necessary.

•Standby/Sleep 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 disabled, 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.

•Standby timers

Each time the drive performs an Active function (such as read, write or seek), the standby timer is reinitialized and begins counting down from its specified delay times to zero. 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.
