Abstract
A hard disk drive includes a flash memory and a rotatable disk. During self-test, self-test data is written first to flash and then later written to the rotatable disk. Since the self-test data is stored in the flash, if there is a power failure the hard disk drive can recover without repeating the test.

14. A method of operating a hard disk drive comprising:
-
during self-test, running a self-test script, the self-test script indicating tests and checkpoints;
when a test is indicated by the self-test script, running test code indicated by the script to do a test in self-test, the test code including statements indicating when to store self-test data;
when the statements in the test code indicate storing the self-test data, storing the self-test data into a non-volatile memory of the hard disk drive; and
when the script indicates a checkpoint, transferring the self-test data from the non-volatile memory to a rotatable disk of the hard disk drive. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
