Data sector relocation method by soft detection dipek

end. The art that the claimed invention: relates to a data sector relocation method of the hard disk drive. I. Technical Problem The invention is to solve: to provide a method by only a soft dipek likely grow the ECC correction capability according to the error rate (Error Rate) which is variable in accordance with a combination characteristic of the head / disk sikimeuroseo variable accurately detected reallocating the data sector have. All. Solution subject matter of the invention: the error according to the according to the number of data sector relocation method through soft dipek detection of a hard disk drive having a data sector having the error correction capability, calculating the error rate during data read, and calculating the error rate while varying the correction rates to the procedure for detecting the soft dipek, if that is not the read error recovery on the detected soft dipek error, the according to the process of executing the error recovery routine for the generated error, and performs the error recovery routine is If the process of confirming that the recovery, and is determined that the above errors are not recovered and then by setting the error correction rates of the maximum repair the error re-assign the data sectors in accordance with the error recovery results with a spare sector or the error recovery results a characterized by constituted by any process of reporting. la. An important use of the invention: It can be used to manage dipek sector of the hard disk drive.
