I've got the machine open again and I've replace the 40 conductor IDE cable with the 80. Still getting the error. From looking at the mobo manual, it looks like I have the SATA drive connected to the SATA channel. THe primary IDE cable is then connected to the DVD and CDR/RW with the DVD at the end of the cable and set as master. Then the other IDE connector goes to the 40G drive which is also jumpered as master. How many ways is this wrong?
