From my personal experience, the situation you describe is what happened when I DID NOT check the box to install OS-9 drivers on a hard drive and then installed OS-X.x first. When I attempted to do a "Clean Install" of OS-9 from a factory install CD v 9.2.1, the machine would not recognize the drive at all. The machine would boot to the OS-9.2.1 CD, but not allow any installation. IMHO, this appears to me to duplicate your main problem. My ultimate solution was to reformat the drive completely and verify that the box was definitely checked to install the OS-9 drivers. Then, I installed the OS-X.x and was able to do a "Clean Install" of OS-9.2.1 without any further problem. Hope this helps.
