[QUOTE="bobtomay, post: 1535213, member: 24160"] If it works in Target Disk Mode and you can see the hard drive and copy from it to the host computer, it is not a hard drive issue. That's what it is for, to allow you to get data from an otherwise non-functioning machine. As the beeps indicate, it is a RAM issue. My best guess based on the spill, would be the slots or the path from the slots have been affected rather than the RAM modules themselves. You can test that by trying the modules in another computer to verify they are working or not. [/QUOTE]
