@Nick thats a slight misconception there. FFS isnt the problem with greater than 4GB HDD's its the scsi.device used, that only has 32bit addressing so it can only address the first 4GB. However FFS did have a limitation in that you could only partition upto 2GB with it, I belive thats no longer a problem with OS3.9, not too sure on 3.5. As someone else mentioned there are ways of getting round the 4GB limit on <=3.1 systems, but ive never looked into it. Personally I dont see why anyone would still be using 3.0 :-)
