I would strongly advise against using partition sizes bigger than 4Gb in
size with PFS3 (that's available file space, so about 4.4Gb-ish in
HDToolBox). Why? Well, I located a bug in PFS3 a while back, which makes
it impossible to format a partition bigger than 4Gb when using debug tools -
these show illegal read/writes to memory. Sure, there are usually no such
problems without using debug tools, and formats work ok, but I find it highly
suspicious that the format would have involved reading random data from
memory that it is not supposed to.

And to confirm my suspicions, I've read about people having problems with
data loss on larger partitions using PFS3 - it might seem ok to begin with,
but problems are almost certain to occur. Unfortunately, the PFS
developers have yet to acknowledge or fix this bug, despite me providing
extensive debug logs and actually pointing out where in their code the
problem was occurring :( I've seen enough Cyberguard logs to know what
I'm talking about, and trust me, there is a problem in PFS3. Whether the
bug does actually cause problems outside formatting, I don't know, but I
know I'm not prepared to risk losing my data on a >4Gb PFS3 partition :)

That said, having stuck with the 4Gb partition size limit, I've found PFS3
to be faultless on my 30Gb drive, and all other drives which I use it on.
I certainly wouldn't swap PFS3 for anything else. But, if you want
partitions larger than 4Gb then you'd be better off using FFS, IMHO.

Sure - as you're using OS3.9, there's no need to use the split option in
order to use larger drives.
