Primary IDE channel no 80 Conductor Cable Installed ??

There are 2 types of IDE cables 40 conductor and 80 conductor. You can tell the difference because the 80 has more and smaller diameter wires than in the 40. The 80 conductor uses 40 more wires that are all grounds, which is necessary to cut down on interference when using with a hard drive. You use 40 wire cables for DVD and CD-rom drives and 80 wire on both Rom drives and hard drives. When you use a 40 wire IDE cable on a hard drive you will get that message,
