This article introduces the relevant knowledge of "how to use MHDD to repair bad track of hard disk". In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

Mhdd is a professional hard disk tool from Russia, when the hard disk appears bad sectors, we can use mhdd to repair the bad sectors of the disk.

How to use:

1. If there are few bad sectors, we can use MHDD software to shield the bad sectors, and unexpected results can be obtained. Take my WD500G notebook as an example to shield the bad sectors of the hard disk.

2, this is my notebook in the recent situation, boot hard disk self-test, hard disk self-test has failed, need to press the space bar before self-test to enter the system normally

At this time, we can scan the hard disk with MHDD and detect the hard disk status.

MHDD Hard Disk Detection Tools are included in the toolbox included in PE. Here, it should be noted that the hard disk mode must be checked in the BIOS of the motherboard to see whether it is AHCI mode or IDE mode. MHDD cannot scan the hard disk when the hard disk is in AHCI mode.

3. Save BIOS settings, restart and press F12 to enter the startup item selection interface.

4, choose 1, that is, my U disk, this need not say more, as long as the reinstallation of the system know how to do

5. Run Hard Disk Memory Detection Scanner Tool Menu

6. Run MHDD hard disk detection

7. The picture is not very clear. Don't think that you are playing too much. My hand is shaking. Don't move here. Just hit Enter.

8. You can see that option 8 is my WD 500G. Press 8 and press Enter. This interface appears.

Start LBA Fill in the start sector of your bad sectors End LBA Fill in the end sector of your bad sectors

Remap is selected ON to enable the repair function.

Timeout is usually the default.

LOOP/TEST REPAIR set to ON means open here is repeated erase can repair play solid bad track.

ERASE is OFF to indicate OFF.

9, the setting is complete, press F4 to start repair.

If you want to cure a disease, you have to see a doctor first. Press F4 directly for a full scan!

10. Enter the hard disk scanning interface, each long square represents 255 sectors (in LBA mode) or 63 sectors (in CHS mode); the scanning process can be terminated at any time by pressing the ESC key; the square from top to bottom indicates from normal to abnormal, and the reading and writing speed is from fast to slow. Under normal circumstances, only the first and second gray squares should appear; if there is a light gray square (the third square), it means that the reading takes more time; if there are green and brown squares (the fourth and fifth squares), it means that the reading is abnormal here, but no bad track has been produced; if there is a red square (the sixth, that is, the last square), it means that the reading is difficult here, and bad track will be produced immediately; if there is a question mark?, It means that there is a reading error here, and there is a serious physical bad track that cannot be repaired. If there is a red X, it means that there is a reading error here, there is a bad track, which can be repaired or shielded.

11, before detection, be sure to prepare paper and pen, remember the location of the hard disk bad track, if the hard disk bad track slightly more, in the lower right corner is displayed endless. As shown in the picture, the bad track position is 91545.

12. After the hard disk scanning is finished, press F4 to appear the interface, select the first item, select start lba, enter 90000, then select remap, type Enter, and turn the option to ON. Remap is to add bad tracks to the bad track interval table. The speed of shielding bad tracks is very fast. If you can't see the shielding process, you will be shielded. According to this method, the remaining bad tracks will also be shielded.

This method is only used for hard disks with less bad sectors, and unexpected results often occur after shielding bad sectors. Finally, don't forget to change the hard disk mode to AHCI mode in the motherboard BIOS!!!

MHDD Low Profile Method

1. Hard disk low format is useful for solving some problems, such as malignant virus and logic bad track.

2. Press the esc key to display this interface, and then enter erase to confirm.

Enter 0 to confirm.

4, then MHDD will repair the bad track of the computer hard disk.
