I have a WindowsXP system with Defraggler 2.14, and while defraggler can defragment the system drive (C:) with no problems, the data drive (D:) can't get below 22% fragmentation. The curious thing is, the drive is not being accessed. All that drive has is the "downloads" directory, and a file-level backup of drive C:; nothing should be active/open on that drive if I am not downloading or backing the system up. But at various times over the past few weeks I have tried defragmenting that driv, and can never get it below 20% fragmentation, even after running the defrag multiple times in sequence.
Have you tried defragging at start-up BEFORE any browsers or other downloaders might launch and take "ownership" ?
. . . the data drive (D:) can't get below 22% fragmentation.
Do you have all these ☑ ticked? . . .
Help me. If you don't access (D:) why bother defragging it, cos the purpose of defragging is to speed access?
I never defrag backups; they are too important to mess with.
