Exactly, the whole this is just MFT.

Actually PerfectDisk 10 can among other optimizations it does at 
Boot-time defrag, and even it changes its size to best fit a partition 
when needed. Unless you have an NTFS encrypted filePerfectDisk 10 
defrags *everything*, this give me the following brag right: don't blame 
me for having the best defragger out there, hehehehe :-D

really? I didn't know this, how do you do this?
