A desktop support technician is troubleshooting a Windows 11 workstation experiencing file write timeouts and suspected storage degradation. From an elevated Command Prompt, the technician needs to run a command that locates physical bad sectors on the OS partition, attempts to recover readable information from those sectors, and repairs filesystem errors. Because the volume is currently locked by operating system processes, the command must prompt to dismount or schedule the scan upon the next system reboot. Which command and switch combination should the technician execute?
- chkdsk C: /rCevap
- Bchkdsk C: /f
- Csfc /scannow
- Dfsck /f C:
Cevap
The command `chkdsk C: /r` should be executed because the `/r` switch includes all functionality of `/f` (repairing filesystem errors) while additionally scanning the disk surface for physical bad sectors and attempting to recover readable data from them.
Executing `chkdsk C: /r` is correct because the `/r` switch instructs the Check Disk utility to locate bad sectors on the physical disk surface and attempt to recover any readable data. In addition, `/r` automatically includes the functionality of `/f` to repair logical filesystem errors. Because the system volume (`C:`) is actively in use by Windows, the command will prompt the user to schedule the scan to run on the next system startup.
