CheckDisk

CheckDisk is a utility that is designed specifically to perform a hard disk health check. You may need it when buying a laptop or computer, or to perform preventive maintenance for your storage system.

Using the program

The program is controlled in the form of a command line. In it you can enter commands to start the test, and its completion. During the test, the utility loads each individual sector of the hard drive to analyze its performance. If there is no response, then the sector is damaged and cannot carry any information. Such broken sectors not only reduce the maximum capacity of the disk, but also make it unstable. By regularly checking the state of the storage system and correcting errors, you can keep your operating system running at maximum performance.

How to work in the program

You need to work in the program by entering special commands through the command line. There are commands to select a separate volume, start testing, check a separate file, and so on. Damage search is available not only on the whole disk, but also on individual clusters. This greatly speeds up the process if there is a lot of data on the disk and you can localize a possible error beforehand. Note that the program can only work with NTFS and FAT disks. At the same time, the commands for different file systems will differ from each other.
