SYMPTOMS
When you run Winternals Defrag Manager to defragment a client computer, some volumes are not detected or defragmented.

Note These volumes are not in the exclusion list of the defragmentation schedule.



CAUSE
This issue occurs because Defrag Manager does not have the necessary permissions to access these volumes.



RESOLUTION
To resolve this problem, verify that both the administrator account that you specify for the defragmentation schedule and the SYSTEM account have Full Access permissions for all the volumes that you want to defragment.

To do this, follow these steps:
 * 1) Right-click a volume, and then click Properties.
 * 2) In the Properties dialog box, click the Security tab.
 * 3) In the Group or User names pane, click Administrators, and then verify that the Full control check box is selected in the Permissions for Administrators pane.
 * 4) In the Group or User names pane, click System, and then verify that the Full control check box is selected in the Permissions for System pane.
