When a computer fails, most users will choose to format or replace the hard drive. However, in fact, hard drive problems caused by logical bad sectors can be repaired and reused without affecting the use of the computer. So what should be done? What? In this tutorial, the editor of Hua Jun will introduce to you a simple processing method:

First we need to look at the causes of logical bad sectors

Logical bad sectors mean that the hard disk is accidentally disturbed during writing, causing ECC errors. From a process perspective, it means that when the hard disk writes data, it will use ECC logic to recombine the data. Generally, the operating system writes 512 bytes, but in fact, the hard disk will write dozens more bytes, and All these bytes must be checked and encoded using ECC. If the ECC correction code calculated by the original bytes is different from the ECC calculated by the read bytes, an ECC error will occur. This is the cause of the so-called logical bad sectors.

Solution to logical bad sectors

In fact, with the tools that come with Windows, we can completely repair the logical bad sectors of the hard disk. We can select the hard drive letter to be processed in "My Computer" under the Windows system environment, select its "Properties", select "Error Checking Status" in the "Tools" button that appears, and then select "Scan Type" Select "Comprehensive Check" and tick "Automatically fix errors", then "Start". If the system does not perform a disk scan at startup or cannot enter the Windows system, we can also use a floppy disk or CD-ROM boot disk to start the computer and run Scandisk under the corresponding drive letter, such as "A:" *: (Note: * is The hard drive letter to be scanned), press Enter and then repair the corresponding hard drive partition that needs to be scanned and repaired.

Just such a step can make your hard drive work again, and it will not affect the use of your computer. Therefore, friends who like computers should learn more about various computer accessories so that they can truly become a computer expert. People, both in use and maintenance. Of course, netizens who have the same experience can still give it a try. Learn more and practice more, and there will be many benefits.
