I'm hoping someone here has run into this problem before. When I try to boot off of OS 9, the happy Mac appears for about 2 seconds, then goes to a flashing disk. Another 1-2 minutes goes by, then the happy Mac comes back...and it just sits there. OS X.2.6 boots just fine (it's on a separate disk drive.) I ran Norton Disk Doctor on the drive (from the OS X drive) and it reported several major errors, but claimed to fix them all. The OS 9 partition mounts under OS X without a problem. I don't have any critical data on the OS9 drive, but I'd like to avoid initializing the disk if I can. Thanks, Eric Volker ebv1 at charter.net
