To stay under the 4GB limit, a 3.7 partition is safer; this is a GB/MB conversion to bytes -- 2 KB is 2048 bytes. When you add a file system, you have to convert the hex number into the ASCII code: PFS/00 IS x50465300 and SFS/02 is x53465302. You also need the correct versions, for FFS to support up to 4Gb, you should use TD64 version such as 45.9 or 45.16, PFS-aio version 18.5 and SFS version 1.277 or 1.279 are the most recent.
