I recently got myself a 400Mhz G4 "Sawtooth", running 10.3.9, & have been looking into SATA controllers etc. At the mo I have an 8gb drive, a 320Gb & a 40Gb one which it boots off. If I put the boot drive in the slot below the DVD it won't start-up at all. If I have it in its' usual place on the bottom of the case it works fine, until I put in the 320, when it doesn't boot at all unless I have the install disc in & it will go to the install menu then freeze. It also works fine with the 8gb drive under the DVD & 40 in its' norm place. Just wanted to ask, is this normal, & is there any way to make it work? I don't really want to spend too much time or money on this thing, endlessly buying RAM, SATA cards, hdd's etc if it isn't going to work. Thanks!
