It will restore the file system on the hard disk
Restoration of the file system on the hard disk may be necessary if it has been damaged or corrupted. Here are some steps you can take to request a recovery:
1. Check the physical condition of the hard disk: make sure that it is connected correctly and that there is no visible damage.
2. Run the error checking tool (chkdsk) in the Windows operating system or fsck (file system check) in Linux/Unix to scan and repair possible problems with the file system.
3. If this did not help, you can use a specialized software product such as TestDisk or EaseUS Partition Master Free for deeper analysis and repair of the MBR (Master Boot Record) file, partition tables, or other data structures on your hard drive.
4. If there are still problems with data access after performing these steps, then the last option will be to seek professional help from the service center for dealing with complex cases of data loss.
However, before starting any of the listed operations, you should create a full backup copy of all important data so that in case of failure you can return to the starting point.
