Tips and warnings

  • The Check Disk utility has three main phases, during which Check Disk initially checks the files, their indexes and finally their security descriptors, and two optional phases when it checks for bad sectors and attempts to recover data.
  • Check Disk can also be run from command prompt by typing "chkdsk".
  • Disk Defragmenter can also be accessed via the Start Menu. To do this, launch the Start Menu, go to All Programs, Accessories and look under System Tools.
  • Both Check Disk and Disk Defragmenter access the hard drive directly, so make sure there's no danger of power outage while the utilities are running, otherwise your disk might be permanently damaged.
