Been using PFS3 most of the time but I gave SFS a try on an A4000 I just put together.
Is it necessary to use SFSFormat to format a partition to take full advantage of SFS?
I used OS3.9 format to format my partitions and it seem to work fine as far as I can tell...

SFSFormat is like PFSformat: you need it if you want to set file system-specific options (caches, del dir etc.). If you don't want to set those options, you can use normal format as well.

Just a small comment regarding this bit...
SFS has the habit of being quite snappy at first. However, it will quickly degrade to unusably slow state (especially if you have a lot of files and/or perform a lot of changes to the filesystem).
SFS also tends to corrupt itself occasionally. In most of the cases the only way to cure it is to copy the data to 2nd partition, reformat and copy the data back.
In my experience PFS3 isn't perfect either, but is clearly better than SFS.

That doesn't sound good :-(
Guess I'll switch to PFS3

I've been using SFS for a couple of years and I've not experienced a deterioration in operating speed. Maybe that's because I don't install/uninstall alot of software or make many changes to my system partition. I have had one corrupt partition though that required a complete reinstall. With PFS3 likely to become open source I think I'll give it a go.

The problem I think with SFS is it gets bogged down with the recycle directory... I've always used SFS with the NORECYCLED option...
I never had any problems with it and when I moved to SFS2 it was VERY fast and still is... I am currently using SFS2 and JXFileSystem4 since I haven't bothered to clean off all my SFS2 partitions and reformat them...
Of course this probably won't apply to you but the tactic regarding SFS is valid... until very recently I never had a problem trying to recover something I accidently deleted... this is the risk I take to make sure my FS is swift and happy... LOL
Just don't remove any sanity checks before carrying out a delete operation (I did) if you still hit the ok button after it asks you if you're sure you want to delete it then by heck you WANT to delete it, surely!

i have to confirm pirus statement alas. i was using it extensively about a year long and it i exactly what happens. to clarify i am not a guy who sets up his hard drives once and never touches them again, but then that is what file system is for: to use it. at the beginnning sfs works wery well. i was really foud of it, then there appear erreors out of nowhere. it is impossible to correct them so either you have to live with them or copy your stuff to somewhere else and reformat. few data might be already lost at this point of course. after about half a year you can expect the partition to give up (happened to me two times a really big way, that means - sys: ). not to count others, but most not frequently accessed drives hold on. i have to add there is no way to rescue the main part of the data from such a lost partition, neither with 68k sfssalv nor under os4. the result is the same for both. with no backup it is almost a total loss.
edit@ piru: could you elaborate a bit what problems pfs has? i was eager to get it but since it was impossible to buy i didnt, and now as soon it is available again i plan to switch to it.

If you delete large amount of data at once you get a "beta warning" requester and the filesystem stops. It's safe to reboot in this condition though, and you'll just end up to the point before the deletion. If you delete the files in smaller chunks, it works ok. IIRC the limit was around 4GB.
