I've done all of those. Perfect Disk just lumps them in the middle of the filesystem. chkdsk /f /x /v /r just takes a long time and tells me I have no errors.
@Judas: Its a problem when you've got alot of DVD images on a 40GB partition and they keep getting massive amounts of fragmentation and things get slower and slower. I'm already running an 'ancient' system here so the extra slowdowns suck.
It might not make that big a difference but it will put my mind at rest
