Why don't some of my NTFS partitions appear in the Diskeeper Tree View?
It is necessary for both SYSTEM and ADMINISTRATOR to have full control over a file (or the directory folder it is in) in order for Diskeeper to have access to move the file. This is because the Diskeeper service runs under the Administrator account, and System access is necessary to safely defragment files. This is a security feature that is governed by the Windows NT C2 security requirements.
If the root-level directory folder does not have SYSTEM and ADMINISTRATOR set for full control (as seen in the Permissions section under the Security tab in the Properties dialog box) Diskeeper will not display the partition in the Tree View under some circumstances.
If it is an NTFS partition the permissions at the root of the drive may not be set correctly. To change the settings do this:
-
Start EXPLORER
-
Right click the root directory for the partition.
-
Click PROPERTIES, click SECURITY, then click PERMISSIONS
-
Highlight ADMINISTRATOR
-
Set TYPE OF ACCESS to FULL CONTROL
-
If SYSTEM is not listed, click ADD and select SYSTEM
-
Highlight SYSTEM
-
Set TYPE OF ACCESS to FULL CONTROL
-
DE-SELECT the REPLACE PERMISSIONS ON EXISTING FILES check box (it is checked by default)
-
Click OK
If Diskeeper still does not display all partitions, you will need to force Diskeeper to refresh its list of partitions. To do this:
-
Close Diskeeper, if it is open
-
Go to Control Panel / Services and stop the Diskeeper service.
-
In the folder ExecSoft/Diskeep/Defrag, delete the file
Diskeep.ctl
-
Reopen Diskeeper
Diskeeper will restart the automatic service and recreate the diskeep.ctl file. The missing partitions will now appear in Diskeeper. Note that any schedules or other preferences you may have entered will be deleted by this procedure, so they will have to be re-entered.
