About the problem of disk bad sector repair, how to fix hard disk bad sector

Use efficiency source hard drive repair.

Physical hard disk bad sectors can be repaired.

It's a good idea to back up your data before doing it.

Or repair in two batches.

Delete the unwanted junk stuff first, put all the important information on the last disk, make a note of how much space this disk occupies, and then go to the efficiency source and use manual repair There are start and end sectors on it.

Let's take a look at what the total sector it counts.

Then divide by the number of g on your hard disk, if your hard disk is 80g, the first three disks occupy 60g, and the data is placed in the last disk 20g, then multiply the number after division by 60, this is the position of the end sector, write down this number, and start repairing.

After the repair is completed, reinstall the system, test the data back to the first 60g, and then use the efficiency source to repair the last 20g, according to the above values, because this repair does not repair the first 60g, so it will not destroy the newly installed system, and the entire hard disk will be OK after repair.

You can't have a question or two, with the Chinese version of the magic partitioner, take a closer look at the tutorial yourself, it's not very difficult. Set up the bad sector area as a separate zone, and then block it with the hidden function in the partitioner.

To save the data. And to restore again. That's more expensive than buying a hard drive.

Find an acquaintance to help you fix it. After all, it's not just software.

It's also about hardware.

Physical bad sectors should be very difficult to fix!

After opening the DOS toolbox, press MHDD to repair and it is OK to repair the files without breaking during the repair process.

Windows itself comes with the ability to detect and deal with bad sectors on hard drives. Take Windows 10 as an example, right-click on the hard disk partition icon, select "Properties", click the "Tools" tab, and click the "Check" button in the "Troubleshooting" item.

Because Windows 10 itself monitors the health of the hard drive, when performing a check, if the faulty partition has been detected, the repair option will be displayed directly. Click Repair, the repair time depends on the size of the problem and the number of bad sectors of the hard disk, but it is much faster than detecting and repairing before entering the operating system, so it is recommended that you detect and repair it as soon as you feel that there is a problem.

When detecting and repairing the problematic partition, if the system prompts that there is indeed a bad sector, then even if the windows prompt does not find the problem, it is necessary to conduct a comprehensive detection of other partitions of the hard disk, because the hardware bad sector may affect multiple partitions, and if it is a physical damage to the disk, it may also scratch the head or expand the damage area when reading and writing, early detection and shielding can avoid storage errors, and also prevent the head from continuing to read and write this area.

In addition, if you use third-party partitioning software, or happen to have these partitioning tools on hand, you can use them to perform a detailed inspection of the hard drive, and you can also find and shield bad sectors. Take diskgenius as an example, select "Disk - Bad Sector Detection and Repair", then go directly to the disk, click "Start Detection", it will detect the entire hard disk surface and determine the health of the sector.

Repair.

The bad sectors of the disk are basically impossible to repair, and the correct way to deal with them is to isolate them. That is to say, don't write any data to the bad track, and jump away from this bad track.
