analyze not matching current state after a defrag

using a laptop with windows 7 64-bit

If I defrag my drive and than analyze again the analyze is alot different than what it said the current state was after the defrag. Is this a bug or what?

current state after a defrag

1 fragmented files

6 fragments

26% fragmentation

analyze again right after and get

5 fragmented files

14 total fragments

29% fragmentation

Have you tried excluding "System Volume Information" from the defrag?

You can't defrag these files as they're in use, and Windows is adding to them as a matter of course, probably through "Shadow Copy", which backups files which are moved or modified.

I excluded the folder now I'll see what I got now.

No my analyze after a defrag is still different after excluding that folder.

Yeah, I'm going to look for a different defrager.
