This article describes how to perform a disk check. This is required to address problems encountered with an operating system as a result of file system errors. Problems can include data loss, virtual machine crashes, slow performance, virtual machine resume and suspend failures, and other unexpected behavior.


Determine if there are problems with your file system by performing a disk check. A disk check can be done by using a 3rd party application or by using tools native to your operating system.
The method of performing a disk check differs between operating systems. Refer to the section below that matches your operating system.


Note: The exact procedure differs between versions of Windows. If one procedure below does not work try the other. If neither method works, consult the manual for your version of Windows.
To perform a disk check from the user interface:
  1. Double-click the My Computer icon.
  2. Right-click the entry for your local disk.
  3. Click Properties.
  4. Click the Tools tab.
  5. Click Check Now.
  6. Select Scan for and attempt recovery of bad sectors.
  7. Click Start.
To perform a disk check from a command line:
  1. Open a command prompt. For more information, see Opening a command or shell prompt (1003892).
  2. Type chkdsk c: /r and press Enter.

    Note: If the local disk being scanned is not c: , replace c: with its drive letter.
Note: A scan of the system drive requires that the operating system be rebooted.


Note: The exact procedure may differ between distributions of Linux. If the following commands do not work for you, consult the manual for your distribution of Linux. The following commands may also fail if you are not logged in as a user with root access.
  1. Open a shell prompt. For more information, see Opening a command or shell prompt (1003892).
  2. Type touch /forcefsck and press Enter.
  3. Type shutdown -r now and press Enter.

    Note: Issuing the shutdown command restarts your operating system.

Mac OS

To perform a disk check:
  1. Go to [Macintosh HD]/Applications/Utilities.
  2. Open Disk Utility by double clicking it.
  3. Click the entry for the disk or volume to check. 
    Note: This is usually the disk which Macintosh HD is indented below. It is named with the size of your harddrive, and the manufacturer's name.
  4. Click Verify Disk.

    Note: You can use this utility to verify the integrity of the startup volume, but not to repair any issues that may be discovered. If you need to repair the disk, use Safe Boot. For more information, see Using Safe Boot (1004017).

    Note: You can also click on Verify Disk Permissions to confirm that there are no problems being experienced due to incorrect permissions. If you find that there are permission problems, they can be corrected by clicking on Repair Disk Permissions.
