Hi Ingo,

 PA>> When you add pfs_aio-handler to the RDB, you should add it as DosType
 PA>> 0x50465303 ("PFS\3"). When you partition the drive and go to the
 PA>> "Change..."  section for a partition, you will then be able to select
 PA>> "PFS\03" as "File System:".

 IJ> Yes, I tried that, but no luck.

What exactly did not work? Adding the file system to the RDB with correct 
DosType or be able to select "PFS\03" as "File System:" in HDToolBox?

It should look like this:

 PA>> Then reboot and do a quick format of the partition. PFS will show a
 PA>> requester when you format it confirming it is formatted using PFS.

 IJ> Nope, no requester. It tried to format it as FFS.

In that case, the "File System:" DosType for that partition must have been 
something else than 0x50465303/"PFS\03". If you attempt to format a partition 
with a non-standard file system DosType from Workbench, you will not get the 
option to select "Fast File System:" and if you format from the shell, the FFS 
switch will not have any effect.

Also always remember to only do quick format if you are under 3.1 as the zero 
writing part of a non-quick format is done by the formatting program itself, 
not the filesystem handler and is not 4GB+ aware and will wrap.

 PA>> OS3.9 is nice and has a more user friendly HDToolBox, however it is
 PA>> not needed if your goal is to use the entire 4GB+ drive with PFS3.

 IJ> So far, OS3.9 is running quite well. Makes me wondering why I refused
 IJ> to update earlier. Maybe because it's not the "original" OS3.1.

I understand what you mean =). I still run 3.1 on a couple of Amigas, like the 
A2000 I am writing this on, as it feels more "original".

Regards,
Patrik
