Well seeing as you kinda hinted rather strongly for me to do something on this thread...
I have successfully used Partition Magic (v8) on NTFS drives. The only times I've had trouble with it is when doing strange things with Linux partitions... Ended up having to format entire drive to get that sorted.
I never have these troubles because having 4 computers in the house, 180GB of hdd space inside my desktop (on 2 drives) and an 80GB external I can just throw files wherever I need them for the format...
I'm not guaranteeing that PM8 will keep your files intact, neither do the publishers as they warn you before you do anything that the hard drive could suffer nuclear meltdown.
Only problem I've ever had with hard drives was when I was defragging 6 drives (3 physical drives & 3 partitions) with Norton Speed Disk similtaneously... It killed the Master Boot Record for the main C drive. Always exciting when you have to use recovery mode or whatever it's called...
