Why each option
Check Disk (chkdsk) scans the file system and disk surface for errors and bad sectors, helping to prevent and resolve read errors on a hard drive.
Check Disk (chkdsk) examines the file system integrity and scans for bad sectors on the hard drive surface. Running it on a regular schedule allows the tool to detect and mark bad sectors before they cause data loss or read errors, and to repair file system inconsistencies proactively.
System Backup copies data to a safe location for recovery but does not scan for or prevent disk read errors.
Disk Defragmentation reorganizes fragmented files to improve access speed but does not check for or repair bad sectors or file system errors.
Windows Update installs OS patches and drivers but has no function for detecting or repairing hard drive read errors.
