Re: FAT95 question

Why use FAT95 on Amiga ?

1) to share the disk with a PC ?
2) to have a maximum of problems ?
3) for fun ?

the real answer is PFS3aio: WinUAE can mount a PFS3 disk, and true Amiga too.

3) for fun (all your data will be erased, this operation of partitionning *MUST* be done before use the harddisk)
Reserve the 2 first blocks (512 bytes per blocks) to figure a MBR (with grub, linux or equivalent) If you are expert in binary block tools, you should make it by hand.
This MBR must describe 2 partitions and ends with 55aa.
partition 1, type 0x1c: RDB stuff + all FFS partitions
partition 2, type 0x83: the fat95 partition
the RDB must start at block 3 (3-15 in fact)
with HDInstTool (or HDToolBox) remap the fat95 partition exactly at the same place.

When the disk is in a true amiga, it will hunt a RDB on the start and skip the MBR.
On a PC, it will ignore amiga partitions and mount the FAT partition.
