Maximum current draw lasts 3.8 seconds. Read/Write Data is being read or written to the drive. Active The drive is spinning and most circuitry is powered on. The drive is capable of responding to read commands in the shortest possible time. Read/Write heads are positioned over the data area. Idle The drive is spinning., the actuator is parked and powered off, and all other circuitry is powered on. The drive is capable of responding to read commands within 40ms. Standby The spin motor is not spinning. The drive will leave this mode upon receipt of a command that requires disk access. The time-out value for this mode is programmable. The buffer is active to accept write data. A program called GREENDRV.ZIP is available on the Maxtor BBS (303-678-2222), that will allow you to program this delayed standby mode. Sleep This is the lowest power state. The interface becomes inactive. A software or hareware reset is required to return the drve to Standby.
