Practice: Maintaining Disks
In this practice, you use the Disk Defragmenter to determine whether your hard disk
is fragmented. If it is, you will defragment your hard disk. You then use Check Disk to
examine your hard disk for file system errors, fix them, locate any bad sectors, and
recover any readable information from those bad sectors. Finally, you use Disk
Cleanup to free up disk space by deleting temporary files and uninstalling programs.
Note If you started with a clean hard disk and installed Windows XP Professional in Chap-
ter 2, these disk maintenance tools will probably not find much to clean up or repair.
