I want to use this same thread since this is still related to my Cube. I ordered a 120GB disk, not knowing if MOS would support a larger drive that OS9 supports. They sent me a 160. I booted the MOS CD and it cannot find the drive. Booting the OS9 CD to install that also didn't find the drive. I put the old drive back in, and it works fine. So, there's something wrong with this disk and I will return it.
