1 Hard disk logical bad sectors can be repaired, while physical bad sectors cannot be repaired. The actual situation is that the bad sector is not divided into logical bad sector and physical bad sector, I don't know who invented these two concepts, anyway, there is no such concept in the technical information provided by the manufacturer, but it is divided into the bad sector recorded by the logical address and the bad sector recorded by the physical address.
2 The hard disk leaves the factory without bad sectors, and the user finds bad sectors that means that the hard disk has entered a dangerous state. The reality is that each hard drive records a certain number of bad sectors before leaving the factory, and some even reach tens of thousands of bad sectors.
3 The hard disk is not saved if it does not recognize the disk, and the 0 track is broken can be solved by partitioning. The reality is that there are a considerable number of hard disks that you don't recognize, and it is difficult to partition when the 0 track is bad.

Before you partition it, you see if you can format it and get rid of it, then you need to fix it with the system maintenance software. Then only in the bad section of the partition can be used without other available partitions, and you don't know after a long time.

Hard disk bad sectors include physical hard disk bad sectors and logical hard disk bad sectors.
If the bad sectors of the logical hard disk can be solved by software, if the bad sectors of the physical hard disk are not easy to pull, you can send them to the computer repair point and ask them to test them for you.
About 50 can be done!~

Find a low-level tool and see if it can be recovered.
0 tracks are broken, and the hard drive is basically finished.
It should be said that there is no way to hide, so you can only find a way to fix it.

Go to "My Computer" and select the bad partition. Right-click Qingzibei, select "Properties", "Tools", "Start Check", and then the "Disk Scan Program" will pop up, select "Completely", and tick "Automatic Repair and Destruction Error", and click "Start".
If the number of bad sectors is not much, you can directly divide a piece of space near the bad sectors into a separate disk when partitioning, and finally delete the partition with bad sectors directly after all the partitions are completed (that is, it will not be displayed as a disk letter), or shield it (many partitioning software have this function). >>>More
