Anne, a user, states her computer is running very slow. On further investigation, a technician sees several disk errors in the event viewer. Which of the following commands would be used to resolve this issue?

Explanation

CHKDSK (Check Disk) is the Windows command-line utility that scans a disk for filesystem errors and bad sectors, and can automatically repair them using the /f (fix errors) and /r (recover readable information from bad sectors) flags. DISKPART is a disk partitioning tool, not a repair utility. FORMAT erases the entire drive, which would destroy user data. SFC (System File Checker) scans and repairs corrupted Windows system files, not disk errors. CHKDSK is the appropriate tool specifically for disk-level errors.
