Running Chkdsk from My Computer or Windows Explorer
In addition to using the command-line version of Chkdsk, you can run Chkdsk from My Computer or Windows Explorer. The graphical version of Chkdsk offers the equivalent of read-only mode, the /f parameter, and the /r parameter.
If Chkdsk cannot lock the volume, you can schedule Autochk to run the next time you restart the computer. You cannot choose to dismount the volume like you can when you use the command-line version of Chkdsk, nor can you use other Chkdsk parameters, such as /c or /i. To take advantage of all the Chkdsk parameters, use the command-line version of Chkdsk.
