Power Mode Definitions Spin up The drive is spinning up following initial application of power and has not yet reached full speed Seek A random access operation by the disk drive Read Write Data is being read from or written to the drive 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 40 ms 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 Sleep This is the lowest power state with the interface set to inactive A software or hardware reset is required to return the drive to the Standby state EPA Energy Star Compliance Maxtor Corporation supports the goals of the U S Environmental Protection Agency s Energy Star program to reduce the electrical power consumption of computer equipment Environmental Limits PARAMETER OPERATING NON OPERATING ST ORAGE Temperature 5 C to 55 C low temperature 40 C high temperature 71 C per MIL STD 810E method 501 3 climatic category hot induced conditions 25 C per hour maximum Thermal Gradient Relative Humidity 5 to 95 non condensing Wet Bulb 30 C maximum Altitude 200 to 10 000 feet 200 to 40 000 feet Acoustic Noise Idle Mode 3 3 be

5. Note The only way to recover from SLEEP MODE is with a software reset or a hardware reset INTERFACE COMMANDS Default Power on Condition The drive s default power on condition is the ACTIVE MODE Upon receiving a Power Mode command except the SLEEP MODE command the drive sets BSY and performs the requested power operation Once the requested Power Mode change has begun the drive resets BSY and generates an interrupt without waiting for the drive to spin up or spin down Upon receiving a SLEEP MODE command the drive is spun down and when it is stopped the drive resets BSY and generates an interrupt When enabling the Automatic Power Down sequence the value placed in the Sector Count register is multiplied by five seconds to obtain the Time out Interval value If no drive commands are received from the host within the Time out Interval the drive automatically enters the STANDBY mode The minimum value is 5 seconds While the drive is in STANDBY MODE any commands received from the host are accepted and executed as they would in normal operation except that the spin motor is started if required to execute a disk command Under these conditions the drive will set BSY when command processing would normally begin and will leave BSY set until the drive comes up to speed and the disk command can be executed Disk commands issued while the drive is in STANDBY MODE restarts the Time out Interval after completing the command A reset must be
