I have an old 5 gb 2.5" HD that has 2 partitions with 2.5gb each.

I want to format modify the partitions size. I can do that in Real A1200 with workbench 3.1 install disk with no problems. But if i try to do it in winuae with classicwb or other OS it cannot recognize any partitions.... But the rest it works fine, after i create the partitions in real A1200, i connect thru usb to winuae and i am able to install classicwb with no problems, loading games etc... the only problem is recognize the partitions... ?
