Hard bad sectors are the ones that are physically damaged , or in a fixed magnetic state. Hard bad sectors cannot be repaired, but they can be prevented.
If you’re experiencing data loss, such as accidental file deletion or file corruption like damaged PST file, you should never run CHKDSK at this time. As we all know, CHKDSK can recognize bad sectors and mark them unworkable.
No, chkdsk /f only fixes disk logical errors where as chkdsk /r also check the drive for bad sectors. Need to mention that bad sectors can’t be fixed since they are actual physical damage to the disk surface. Need to mention download FL Studio that you don’t need to run a chkdsk /r commasnd unless you think the target hard drive has physically bad sectors.

Thereby, it erases the accidentally deleted file from the drive permanently, not to mention to recover it.
chkdsk /f /r command will fix found errors in disk and then locate bad sectors and recover readable information from bad sectors, while chkdsk /r /f conducts these tasks in the opposite order. This post focuses on the differences between CHKDSK /f and CHKDSK /r.
Do not run chkdsk /r as it is not necessary to check for bad sectors. The intensive disk activity for the check is unnecessary wear on the SSD, and is generally recognised as a bad idea. HDD Regenerator scans and attempts to repair any bad sectors on a given hard drive. Chkdsk /f is a Command Prompt command that is used to check a target drive on your computer and fix any hard drive errors it detects.
