CMD
Low risk
Administrator required
Analyze Windows volume without restarting
Launches an online file system scan of C drive without immediately planning off-line repair.
chkdsk C: /scanWhen should you use it?
Use this for file errors, NTFS warnings, or suspected logical filesystem corruption.
What the script does
- The /scan option performs an online scan on recent Windows versions.
- The result indicates whether additional repair is required.
Precautions
- This test does not replace SMART hardware diagnostics for a suspect disk.
- Back up important data if errors are detected.
Rollback
The scan alone normally does not modify data.
