ABSTRACT:
A hard disk drive system comprises N hard disk drive means for performing hard disk drive functions and is connected in a daisy chain, wherein N is greater than one. The system includes integrated system test (IST) means for testing and that is integrated with a first one of the N hard disk drive means and includes pattern generating means for generating test pattern data and pattern monitoring means for receiving a returned test pattern. The pattern generating means generates test pattern data that is routed from the first one of the N hard disk drive means serially through the remaining ones of the N hard disk drive means and back to the first one of the N hard disk drive means. The pattern monitoring means generates test result data based on returned test data returned to the first one of the N hard disk drive means.
