Well I asked AmigaOS 4 developers about this issue as well. Lets see what
they say about 2 TB limits.
16 TB = 2 TB * 8. Perhaps they increased the block size from 512 to 4096?
block/partitions/amiga.c reads the block size from
RigidDiskBlock.rdb_BlockBytes,
but after conversion to 512-byte blocks, all further calculations are done on
"int", so it will overflow for disks larger than 2 TiB.
Note that in your profile-binary.img, the field is 0x200, i.e. 512
bytes per block,
so I'll have to get a deeper look into your RDB first...
