I actually wouldn't defrag an FFS partition since I had Reorg destroy my hard disk one time when it crashed half way through.
I'd probably just go for either SFS or PFS. Both have online defragmentation and I would trust it more.
I'm pretty sure SFS doesn't defragment itself. It certainly didn't defragment my drive when I had two 1.6GB partitions.
I had ReOrg crash my drive as well (many years ago)...it was my own fault though, ReOrg is actually a fantastic program. :cool:
