I've used Defraggler 2.09 for days on end on production database servers (Windows Server 2003/8 R2 on Dell 2950, R710, R910, etc.), without any known issues. Recently, I tried 2.10 on a Hyper-V host server (Windows Server 2008 R2, Dell R510, the C: drive), and was unable to start a Hyper-V guest because it was unable to access their equivalent of a REDO file (odd, since I thought the guest had been shut down, not suspended). As soon as I stopped Defraggler, the guest was able to start. Unfortunately, that's a production box, so I'm generally unable to repeat any tests, but I did want to report the time correlation of these events.

I do a lot of photo editing, so I end up with directories of a thousand or so 20MB files, plus a 200MB or more cache file. These files are updated, randomly, frequently. I'd like to make sure that the entire directory was stored contiguously on the disk... and, for that matter, it would be _very_ nice to be able to tag some directory hierarchies "go to the end of the disk (inner track)" and others "go to the front of the disk (outer tracks)".
