How many devices do you have on your chain? Remember:
* One device must provide TermPower
* BOTH ends of the chain must be terminated. I.e.
Terminator (no TermPower) -> CSPPC -> Hard Disk (Terminated with TermPower)
will work. However:
CSPPC -> Hard Disk (Terminated with TermPower)
will NOT work because one end is unterminated.
My system has SFS, PFS3 and FFS on it - the PFS3 partitions don't work outside the first 2GB or something, but they don't stop the rest working...
