Syntax

chkdsk [options] c:
chkdsk /r /f c:

Options:

  • /f to force a lock on the drive and fix errors
  • /r to attempt recovery of bad sectors (takes longer)
  • /perf uses more system resources to complete faster (works only on NTFS drives), use this if not using the computer while its running

I have a reminder to run this every 2 months on my internal drives and any external hard drives and SSDs as a form of preventative maintenance / early warning for impending drive failures.
