While troubleshooting a failing Windows 10 desktop, you decide to run the command chkdsk C: /r overnight. Which specific action does the /r parameter instruct CHKDSK to perform during its scan?
Displays the full path and name of every file on the disk
Uses more system resources to perform a scan as fast as possible
Locates bad sectors and recovers readable information
The /r parameter tells CHKDSK to read every sector on the volume, identify any that are physically bad, and attempt to move or rebuild data found in those sectors. Because this process also implies the /f switch, CHKDSK first locks the volume, then fixes logical file-system errors, and finally tries to recover readable information from the bad areas. Other switches serve different purposes: /v lists every file, /perf uses more resources for a faster scan, and no available switch merely "displays cleanup messages."
