Issues with installing software on PFS

[CritAnime]

I have got my hands on a boxed copy of Easy AMOS but I am having issues installing it onto my PFS formatted CF HDD. On my FFS CF HDD, which I use for games, it installs fine but the PFS formatted card Easy AMOS keeps saying the destination drive is full. Even though I have 800mb free.
 
This is not the only bit of software I have issues with. X-COM also does this along with Frontier Elite II (I used these for testing).
 
It's annoying because I use one card for productivity, and also for teaching myself about programming, and another for simply playing whdload and installed games.
 
I have the max transfer set correctly and have had no other issues with the drive other than trying to install things.

Cheers for the help guys. With some tender love I got xcom and frontier elite to install. Easy AMOS I had nothing but trouble with. In the end just to give me less of a headache I formatted the card and I put SFS on it and it installed first time.
 
The RAM patch worked great though and thats how I got xcom to install in the end.
