I recently bought a 120GB hard drive for my G4 400Mhz Sawtooth. I put it in my system and set it to slave. I left the factory 20GB in there set to master. I want to install Panther soon as my main operating system leaving 9 on the 20GB as backup. I'll also install 9.2.2 on the slave drive because I still have some programs that will need to start up classic to run. Will this set up work? Is there any problem with running X as the main operating system from a slave drive as long as I set that drive as the boot drive? Or should I change the jumpers on the two drives and make the 120 GB the master and the factory 20GB the slave? I haven't formatted the 120GB yet, as I thought I'd use the OS X disk to partition it when I install. Thanks, Lynn
