Defragmentation Problems

Check your hard disk for errors

You can solve some computer problems and improve the performance of your computer by making sure that your hard disk has no errors.

1. Go to Start and Open Computer.
2. Right-click the hard disk that you want to check, and then click Properties.
3. Click the Tools tab, and then, under Error-checking, click Check now.
   
   If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
   To automatically repair problems with files and folders that the scan detects, select Automatically fix file system errors. Otherwise, the disk check will report problems but not fix them.
   To perform a thorough disk check, select Scan for and attempt recovery of bad sectors. This scan attempts to find and repair physical errors on the hard disk itself, and it can take much longer to complete.
   To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.
4. Click Start.

Depending on the size of your hard disk, this might take several minutes. For best results, don't use your computer for any other tasks while it is checking for errors.
Note

• If you select Automatically fix file system errors for a disk that is in use (for example, the partition that contains Windows), you'll be prompted to reschedule the disk check for the next time you restart your computer.
