does vista b2 defrag work

Okay, I've heard here and elsewhere that it doesn't work and I'm curious. The claim its not working is to defrag in Vista and then use a defrag in XP if you dual boot and it will say the drives do need it. Now, my confusion is, is that if you do the same thing in XP after a defrag with program X and then check with program Y, the same thing will happen since no defrag uses the same algorithms and placement schemes when defragging. So does it or does it not work?

What happens when you try it? Isn't the idea of the beta for us to try stuff and give bug reports to MS.

Windows Vista defrag works fine.
Just as you theorized, it uses a different algorithm than XP's, which is why XP will sometimes say that a Vista drive needs defragged right after Vista has defragged it.

from a command prompt, type in defrag "drive" /a
forces an analyze of the drive, check the fragment %. then say that defrag works.
have run it as many as 4 times with no change in %.
