Abstract
Disclosed is a disk drive test system to simulate a power trip to a disk drive, a cell, and a test computer. The disk drive test system comprises: a disk drive coupled to a cell, a test computer coupled to the cell and the disk drive, and a power trip simulator. The power strip simulator is coupled to the disk drive and the test computer and is configured to cut off power to the test computer, the cell, and the disk drive in response to a trigger pulse received from the disk drive, wherein the power trip simulator restores power to the test computer, the cell, and the disk drive after a pre-set time duration.
Claims16
A disk drive test system to simulate a power trip, the disk drive test system comprising:
- a disk drive coupled to a cell;
- a test computer coupled to the cell and the disk drive;
- and
- a power trip simulator coupled to the disk drive and the test computer, the power trip simulator configured to cut off power to the test computer, the cell, and the disk drive in response to a trigger pulse received from the disk drive, wherein the power trip simulator restores power to the test computer, the cell, and the disk drive after a pre-set time duration,
- wherein code to instruct the disk drive to transmit the trigger pulse is transmitted from the test computer to the disk drive and is stored in a flash memory of the disk drive.
A method to simulate a power trip, the method comprising:
- transmitting a trigger pulse from a disk drive to a power trip simulator;
- simulating a power trip to the disk drive and a test computer by cutting off power to the test computer and the disk drive by the power trip simulator;
- and
- restoring power with the power trip simulator to the test computer and the disk drive after a pre-set time duration,
- wherein code to instruct the disk drive to transmit the trigger pulse is transmitted from the test computer to the disk drive and is stored in a flash memory of the disk drive.
