Zip Drive Question:

Once the Zip disk drive has been installed into the computer, connect the IDE/EIDE interface cable to the back of the zip drive. Almost always the red or blue side of the cable represents PIN 1 and is connected with the colored side of the cable facing the power connection.
Once the IDE/EIDE cable has been connected to the back of the Zip drive, connect the power cable to the back of the drive. This cable is almost always keyed and only goes in one direction.
