System Agent Reports Error After Running ScanDisk

You may receive the following message after System Agent runs ScanDisk:

This message indicates that a drive could not be checked by ScanDisk because it was locked by another program, or because it was created using the SUBST command.

Make sure that no drive is locked by another program, and then run ScanDisk again.

Note that ScanDisk cannot check drives created using the SUBST command.

The behavior described in this article can also occur if you have scheduled both ScanDisk and Disk Defragmenter to start when you start Windows 95. Both programs try to lock the drive at the same time instead of one program running after another. Schedule ScanDisk and Disk Defragmenter to run at different times.
