Defragging Vista Home Premium - Diskeeper v PerfectDisk

Defrag Diskeeper 2008 Pro versus PerfectDisk 2008 Pro

Having used Diskeeper 2008 Pro I noted a marginal preference expressed on this NG for PerfectDisk 2008 Pro, so I uninstalled Diskeeper and installed PerfectDisk on 30 day trial.

In use I felt that the PD approach of getting the most used files to the edge of the disk to reduce the amount of file movement was a good idea and there seemed to be some slight improvement in speed. However when I set a boot time defrag, a low level error message came up something like "Unable to gain exclusive access to drive C", chkdsk was not run, and no boot time defrag took place as far as I could tell.

After a couple of days I uninstalled PerfectDisk and reinstalled Diskeeper whose boot time defrag still worked perfectly, but booting was slow and accompanied by an error message something like PDBoot.exe not found - skipping autocheck.

So I was generally impressed with PerfectDisk, but disappointed that it couldn't perform a boot time defrag and that it failed to remove all traces of itself when uninstalled.

But that leaves me with the nagging thought - could it have been that it was Diskeeper that failed to uninstall cleanly, making PerfectDisk "Unable to gain exclusive access to drive C"? Or is it a Vista problem?

Has anyone here mastered boot time defragging with PerfectDisk 2008 Pro?
