Can I do a partition to hard drive wich already has a 3 FFS partitions?
I made a 100mb partion, choosed advance options updated new filesysten l:fat95 DosType = 0x46415401, wich is a problem. :(
Wich one I should use? I will have 3 FFS partitions first or do I need to make it as second partition.
DosType = 0x46415400 /* floppies only. Or else... */
DosType = 0x46415401 /* first usable partition. Works almost always. */
DosType = 0x46415402 /* second "primary" Partition. Seldomly. */
DosType = 0x46415405 /* first "logical drive". */
DosType = 0x46415406 /* second "logical drive", etc. */

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.

I would like to see inside of my Bridgeboard FAT partition, for easy file transfer between systems Amiga <-> Bridgeoboard.
I think that I'l try this
