I second the spare parts threat... no need. As for the cable pinout, I may have it with me (I just flew into Seattle from Virginia for the holidays). If I don't then I can email the connection scheme when I get back after the 2nd of January. I detailed not only the external cable, but the internal cable to make the internal drive a double density. I can send iPDS disks after I get back on the 2nd also. I'm with Dave, no need to replace the internal drive. Leave all the hardware as-is for now. The double density is the controller - not the drive. best regards, Steve Thatcher
