This problem occurs because the Chkdsk.exe utility or the Autochk.exe utility could not lock the partition. This problem can occur if another utility or service, such as a virus checker program or a disk monitoring program, locks the partition before you try to run the Chkdsk.exe utility or the Autochk.exe utility.

1. Click Start, point to Settings, and then click Control Panel.

To resolve this problem on a Windows NT-based computer, follow these steps:

   1. Click Start, point to Settings, click Control Panel, and then double-click System.
