Win7 defrag v Defraggler

[Merlin5]

Win7 analysis gives me 3% fragmented on my main C drive, and 0% fragmented on my smaller E and F drives.

Defraggler gives me 11% fragmented on C, 15% on E, 55% on F.

I wasn't aware of this until Phil2008 told me that windows defrag is no good and that I should try Defraggler. So all this time I thought my drives were barely fragmented.

How can windows defrag be so wrong?

Thanks Captain Crash. So are you saying that I can just go with the windows analysis of 3% fragmentation of my C drive because that's all that is necessary for any performance benefit, and that I don't really need to see or defrag the files that defraggler is showing?

Thanks for the advice chaps.
