I mentioned in another thread that I've picked up an old 20sc hard drive recently. What machine could I connect this to to test if it's functioning properly? Rattle off some model numbers please... I'm new to mac ownership, but used them throughout my education. Also, what's some good diagnostic software for external devices such as this? I'm guessing I may have to format the drive also before it's ready to use. Anything I can download off the web? What about hooking it up to a PC, and formatting for macintosh somehow? Ideas, people?
