I can try the drive in question in my G3 b&w, but I'll have to clear out enough space to get inside to make the switch. Other than the oversized 5 inch hard drive from an ancient PC (which mounts, but has a weird jumperless setup), all I have available (that I know definitely works) is a 120gb drive I was going to swap into the b&w. I'm not sure if something with that large of a capacity will even work... what is the max capacity when it comes to Macs of that era?
