|I analyze the hard drive with the Windows defrag utility ,however I use Defraggler to do the actual defragging. |
There's where your problem lies. Analysing with one utility and doing the job with another is a sure way to end up chasing your own tail.
Each utility will have a different algorithm for determine what needs dragging and how to do it. If you are going to use a separate utility to do the dragging use that and only that. Don't use the Microsoft tool to determine when you should do it as it will always give you misleading results unless you actually use that to do the defragging.
What LBA compliance has got to do with this I have no idea. Different problem altogether.
