I have a PowerMac G5 dual 1.8GHz model. I picked up a new 500GB SATA WD blue hard drive to replace the original. I popped the drive in and started up off the DVD to install 10.5. The disk utility refuses to see the drive. I tested it in another machine and it shows up just fine, so I don't believe it's bad. I noticed the original drive in the G5 has a jumper installed, I wasn't aware that SATA drives needed that set even on older machines? Anyway, the new WD drive has a spot for jumpers but there is no map explaining what the various settings are. Anyone have experience with replacing the drive in a G5?
