Abstract
The invention discloses a hard disk scanning detection method, and the method comprises the following steps: issuing a data reading command to a hard disk, finding a hard disk bad track of which datacannot be read, performing state marking on a bad track sector by using an ECC mechanism, performing Remap processing on the data on the sector, and recovering the data to a good sector. According tothe invention, the defect of incomplete scanning range of a random scanning method is avoided, and each sector of the hard disk can be scanned; the defect that a full-disk scanning method is not flexible enough is overcome, and hard disk bad tracks can be found more quickly; the CPU burden can be reduced, and the use cost of a user is reduced.
