3Select your chkdsk options. You can decide if you want chkdsk to fix errors and recover bad sectors. If you check either box, and you are trying to scan the hard drive that your operating system uses, then it will prompt you to restart. If you do, chkdsk will launch before Windows starts.
- You must be logged in as an Administrator.
Method 2 of 3:Through the Command Prompt
1Restart your computer. As the computer boots up, repeatedly hit the F8 key until the Advanced Boot Options appear. This menu allows you to boot to a command prompt without loading Windows.

3Run chkdsk. Type “chkdsk” and press enter to run a check on the current drive without fixing any errors.
- To run chkdsk and fix errors, type “chkdsk c:/f” Replace “c” with the drive letter you would like to fix.
- To run chkdsk and fix errors, locate sectors and retrieve data, type “chkdsk c:/r” Replace “c” with the drive letter you would like to fix.
- You may be prompted to restart if the drive is in use. If prompted, press Y to accept.

1Launch Disk Utility. Disk Utility provides the same basic functionality as Chkdsk does for Windows machines. You will need a Mac OS X installation DVD.
2Turn on the Mac and insert the CD. Hold down the “C” key. This will load the setup program for Mac OS. Choose your language to continue.
3Open Disk Utility. You can find it in the desktop menu bar. Select the hard drive you wish to repair and click Repair Volume.
