When attempting to perform a boot time or offline defragmentation pass, I get a failed to open message, driver conflict message or Windows fails to start.
3rd party programs may modify the BootExecute registry key so that PDBoot.exe is no longer the first entry. PDBoot.exe needs to be the first entry in order for the PerfectDisk boot time defrag to run correctly. To verify that the BootExecute registry key is correct, do the following:
- Click on Product Resources
- Click Support
- Click the Start button to initiate diagnostics
- If any issues are identified, click Fix to resolve
If no issues are identified/fixed, please see below for other reasons why the boot time defrag may not be running.
The following 3rd party products have drivers that open the drive for write access prior to PerfectDisk's boot time defrag being able to mount the drive for exclusive access. If the drive has been opened for write access, for safety reasons PerfectDisk will not perform the boot time defrag. Depending on the 3rd party product, you may either see a "failed to open" message from PerfectDisk or a "possible driver conflict" message on the screen. There may be other products not listed below that prevent PerfectDisk's boot time defrag from running.
