Can I get statistics about the Fragmentation of a drive on Windows Vista? The Defrag utility only allows me to defrag and adjust the schedule, but I'm missing the statistics that older Windows Versions had...

You could use auslogics, it's free, gives you the stats and I find it does a better job that windows defrag.

Not exactly what I was looking for, but still upvoting and accepting because it has the one function I really want: The ability to defrag a single folder, and it's free - Nice! – Michael Stum Jul 19 '09 at 0:02

Just found it here. It's required to use the defrag.exe command line tool with Admin permissions.

    Note: On NTFS volumes, file fragments larger than 64MB are not
    included in the fragmentation statistics

    You should defragment this volume.

MyDefrag is the just-released successor to JkDefrag. It has an analyze feature that is comparable to that of Windows XP defrag.
