Nowadays, a computer is perceived as ordinary household appliances, the presence of which in every house no longer surprises anyone. But this was not always so. Surely most readers will recall how miraculously just recently there was a computer of its own, which stood like a car.

If you read carefully, you were probably surprised to find information about fixing even physical errors on the surface of hard drives. No, the program does not send nanorobots there, but it can mark “bad” sections with a special marker.
As a result, the OS no longer writes any information to these cells. We remind you that the SCANDISK utility was responsible for performing this work in early versions of the Microsoft operating system.In general, if you run the utility with the checkbox selected for detecting and correcting physical errors, get ready to wait a long time. It is best to leave this operation overnight, without touching the computer during its execution.

Naturally, the next time you reboot, the disk check program should be launched, but with the old XP this does not always work out smoothly. Even if at the start of the CHKDSK system (what we already learned) it did not start automatically, it is better to start it in a forced manner.
The fact is that errors in the file system (and they almost always appear during an emergency shutdown) can manifest themselves suddenly and completely unexpectedly. This can be expressed in the inappropriate behavior of the OS, in crashes and improper operation of applications.
Run from the command line
Above, we have already described the simplest way with which you can run such a useful utility. But we would recommend doing this in command line emulation mode . For what?

How will the CHKDSK program run in this case? Parameters in this case are set by the letter "F". It means that the utility will detect and correct only logical errors on the hard drive. If you put the / v option there (chkdsk with: / v), the utility will first display all the directories that will be scanned.
In the event that you are interested in finding and repairing damaged sectors of the hard drive, put / r at the end of the command. The value of this parameter is that the utility starts not only searching for this kind of problems, but also tries to save the data that is still possible to read from the bad sections.Important!

It often happens that there is not enough time for technological operations. Is there any way to reduce the execution time of the CHKDSK utility? Options allow this. Just enter this command line: chkdsk with: / i. In this case, the check will be performed with less thorough checking of the index entries.
Attention! This option should also be used only with disks on the NTFS file system. So before starting the CHKDSK utility, we strongly recommend that you double-check everything again.
It must be remembered that there are many commands and conditions for their use. To fully characterize them all, the volume of this article is clearly not enough. If you want to know more about some parameters, then use the following command: chkdsk with: / ?. In this case, a completely detailed help will appear on the command line., - . , ! , , : « ».
