The repair method of the hard disk can recognize the abnormal sound

The hard drive can identify the correct parameters, but in the process of recognition of the different sound, this situation is the SA area has a bad way, directly with SELFSACN can be effective immediately, SF can scan sa area bad road to Uba bad Road table (not P table OH), if not the key module absolutely fix, It is not possible to recognize the correct parameters if it is a key module hard drive.

Note that: The original firmware version of the hard drive must be guaranteed to be correct, it is best to do not brush the firmware to do the backup immediately after the SF, the original disk of the firmware is generally correct, just a problem with a module. The advantage of SF is that sometimes even a large number of bad ways can be used to knock the plate.

In the second case, there is a non 0 head damage, then SF is impossible to complete correctly, you can load less a head of the Ldr file to try, such as 33073h3 load 32049h2 LDR, the premise is the First circuit board number is the same, otherwise you can knock Non-stop, preferably HDA number and compile code are the same, The 1E module is then written to the original disk to solve the speed problem, such as reduced success capacity. If the center of the head is damaged, you can only edit the firmware file to complete, no more details here.

The third case is a large number of bad-side cylinders, you can use MHDD scan to the location of the disc, with the addition of 2.01 module plus LBA method of the whole block added to the P table, do not relent, add a hundred or even hundreds of, and then use MHDD erase bad area to try, also very effective. Note that the original disc firmware must be backed up, in the course of the operation must be the hard drive side, to prevent the expansion of bad areas, or you can not regret the medicine to eat!
