My observation is that it means that there is NO OS 9 driver installed. The check box used to be available or not depending on whether or not your machine could run OS 9. (I think; this is based on some simple observations.) More recent OS X Disk Utility applications include the OS 9 switch all the time. It's useful for formatting FireWire drives that may be used on 9. Again, this is all observation concerning Disk Utility. I may be wrong. ...Duane
