Several years ago I got a Mac Alley replacement mouse for my MDD 867. The mouse came with an installation disc, so I ran the installer and found that the original OS9.2.2 installation was no longer accessible.
I could still run Classic but could not boot back into OS9. It seems that other people have had the same problem with Mac Alley. I sent several emails to Mac Alley but never got any replies. I installed OS 9 on another disc and everything was working fine until the disc died the other day (stupid Seagate drives). Is there any way to repair the original OS 9 installation on the boot drive or do I need to do another install on another partition?
