Could be missing:
- Did you format the second partition?
- What file system did you use on it? SFS is not good for unexpanded (without accelerator) Amigas.
- What ROM version you have? 37300 is no good at all for big partitions! What is the size of the HD/CF? Bigger than 2Gb will put you into trouble if you don't have a 3.1 ROM in your A600 (compatibility for up to 4Gb without patches).
