A utility called Disk Utility was created by Apple to ease the users with several of the disk related tasks like creation, conversion, compression and encryption of disk images, verifying disk integrity, checking the SMART status, mounting, unmounting and ejecting disks, verifying and repairing permissions and lots many.

But the error message which announces like:

"Disk Utility Internal Error.

Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility."

may shake the mind of the user. This error message appears on the screen when the user attempts to repair the permissions.

As the error message indicates, this may be a DiskManagementTool related problem when it encounters a particular file called Chess. If so then it is better to remove that file. Another thing which can be tried out is to use Repair Disk after booting from the CD.
