It just gets even worse when SFS doesn't have proper repair tools. Once you've copied your data back and forth couple of times, each time being forced to reformat, I'd guess you might get a bit irritated.
I'm sorry, but when most people *don't* have that problem, I tend to believe that it is the user's computer that is at fault. Be it hardware problems/incompatibilities, or hacks corrupting memory, or some other software that is interacting badly with SFS, etc.
I just think it is wrong to say "SFS is aweful, PFS is wonderful". They both have good and bad points, and I have used both without problems.
Never had a single problem with long filenames, and I have lots of them.
I am talking about names that are (say) 100+ characters long, although anything over 32 was risky. Any time I used excessively long files names, that file (if not the whole damn directory) became corrupt/unreadable (and once the entire partition was {bleep}ed).
I have used AFS, PFS, PFS2 & PFS3 :-)
