3.10. Checking a Volume for Errors


You want to check a volume for errors.


Using a graphical user interface

  1. Open Windows Explorer.

  2. Right-click the drive you want to defragment and select Properties.

  3. Click the Tools tab.

  4. Under Error-checking, click the Check Now button.

  5. If you want to fix any file system errors that are found, check the box beside Automatically fix file system errors. If you want to perform a thorough scan of the disk and check for bad sectors, check the box beside Scan for an attempt recovery of bad sectors.

  6. Check the disk options you want and click Start.

  7. Click OK when the check completes.

> chkdsk D:

Use the /f option to have chkdsk attempt to fix any errors it finds:

> chkdsk D: /f

With the /f option, chkdsk will try to lock the drive, so if it is in use by another process, you will only be able to schedule it to run during the next reboot. You can include the /x option with /f to force the volume to be dismounted (for a nonsystem volume).

Using VBScript

' This code tries to perform a chkdsk on the specified volume.
strComputer = "."
strDrive = "<Drive>" ' e.g., D: boolFixErrors = True ' True = chkdsk /f, False = chkdsk ' ------ END CONFIGURATION --------- set objWMI = GetObject("winmgmts:\\" & strComputer & "\root\cimv2") set objDisk ...
