Talking about whether the hard disk has a precursor before the bad track occurs

        Generally speaking, hard disk bad sectors are divided into logical bad sectors and physical bad sectors. The former is soft bad sectors, usually caused by improper operation or improper use of software, and can be repaired by software; the latter is a real physical bad track. Indicates that physical damage has occurred on your hard disk track and can only be resolved by changing the usage of the hard disk partition or sector. The following situations may have bad sectors on your hard disk:

First you hard disk operating speed slow when you open, run or copy a file, and there may be a long operation is not successful or performance Long-term death "啃" in an area or a hard disk read disk abnormal sound, or simply Windows system prompts "can not read or write the file", these can indicate that some parts of your hard disk have bad sectors.

Secondly, each time you switch, Scandisk disk automatically run, certainly indicates that there is an important need to fix errors on your hard disk, such as bad sectors. If you can't pass the program successfully, it means that the hard drive must have bad sectors. Of course, the scan can pass, but the red "B" mark indicates that it also has bad sectors.

Third, the hard disk can not boot the computer starts with a floppy disk or CD-ROM drive letter can be seen but can not operate or make a mistake or simply can not see the letter after the start of the area, indicate on your hard disk There may be bad sectors. Specific performance, such as during the boot self-test, the screen prompts "Harddiskdrivefailure" "Harddrivecontrollerfailure" or similar information, you can judge the hard drive or hard disk controller hardware failure; when reading and writing the hard disk, prompt "Sectornotfound" or "GeneralerrorinreadingdriveC" and other similar error messages , indicating physical damage to the hard disk track.

Finally, the computer crashes or "The file is corrupted" and other issues during normal operation, and may also be related to hard disk damage. Hard disk is relatively easy to damage hardware in computer hardware, especially our traditional mechanical hard disk. In the process of use, the most taboo is intense vibration, so when using the computer, it is best not to move the computer, otherwise it will easily damage the hard disk. .
