ABSTRACT:
A hard disk drive with a reduced read channel optimization test time and a reduced test time difference determines whether or not the time limit for testing the hard disk drive has elapsed whenever the test by the zones and heads is completed, so that the test time difference between the respective drives may be prevented. Further, the test progresses from the last zone to the first zone. Thus, although the test is halted in the course of performing the test, the zone with the high error rate can be tested. In addition, a determination is made as to whether or not the error rate is high or not at the steps of selecting the test track and determining the test off-track. If it is determined that the error rate is high, the total number of sectors to be read for the test will be adjusted, thereby reducing the test time delay due to the high error rate.
