PURPOSE: A burn-in/final test method for improving the yield of an HDD(Hard Disk Drive) fabrication process is provided to simultaneously perform a burn-in test process for previously searching a defect to avoid the defect and a final test process for confirming whether an HDD set is normally processed without a defect, thereby improving the yield of an HDD fabrication process. CONSTITUTION: When burn-in and final test commands are received, plural test computers perform burn-in tests for a plurality of HDDs(700). A host computer detects whether the burn-in tests of the test computers are completed(710). If so, the host computer receives burn-in test results on the HDDs from the test computers to store the results, and outputs result values to a display(720,730). The host computer generates a control command for a final test of testing a defect processing state(740). The host computer detects whether the test computers complete the final test(750). If so, the host computer receives final test results to store the results, and outputs result values to the display(760,770).
