ABSTRACT:
A method for testing a hard disk drive is described. The method includes determining a number of defects associated with a portion of recordable media associated with a hard disk drive. The method further includes comparing the number of determined defects to a threshold number of defects and provided the number of determined defects is greater than the threshold number of defects, determining that the portion of the disk comprises disk defects.
