The correct answer is D. Run CHKDSK (Check Disk).
* CHKDSK is a command-line utility that scans and repairs file system errors and bad sectors on a disk.
Running this tool first can determine whether the hard drive is experiencing file system corruption or physical failure.
* If CHKDSK reports bad sectors or extensive corruption, it indicates that the drive is failing, and data backup should be performed immediately before replacing the drive.
* Syntax Example:
chkdsk /f /r
* /f - Fixes file system errors.
* /r - Locates bad sectors and recovers readable information.
Why Other Options Are Incorrect:
* A. Perform a System Restore - System Restore can revert system settings, but it does not fix hardware issues like a failing hard drive.
* B. Open Disk Cleanup - Disk Cleanup removes temporary files but does not diagnose or repair disk issues.
* C. Replace the hard drive - While replacement may be necessary, a technician should first diagnose the issue using CHKDSK before determining if the drive needs to be replaced.
