i should add that the latest versions of all of them do repairs to osx as well. so they are not just for fixing os 9 problems. The only osx native running repair program is Drive10. I have it and it seems to work pretty good. but a lot of other people seem to have been having problems with it. I use it less and less as a result.
good luck. feel free to ask me any specific questions you still have.
oh and another solution for running the repair programs. put it on your osx drive. then boot from any os 9 cd. If your os 9 drive mounts during this, then it is the osx drive that is having recognition problems and you need to repair it as well. maybe only it, but i would fix both to be safe.
