Windows doesnt see it as it was formatted to amiga, but it is in the bios i was thinking format it as windows hd to get winuae to see it again but windows cant see it so i cant select it to format in either situation,
Windows must NOT see the drive. If you're going to format you must do it inside the emulation. Also, it's quite pointless to wait for the "full format", always choose "quick", it takes only couple of seconds instead of (potentially) hours.
