|I had ask for the Make and Model of the computer, not the HDD.|
There is a wide ribbon cable attach to the HDD. Other end is plugged into a socket on the motherboard. If the motherboard has another similar socket adjacent to that one, then that spare
socket should be the IDE 2. If so, then you need another ribbon cable to plug in there.
NOTE that one wire at the side of the cable has a RED line on the insulation. Make sure both ribbon plugs are orientated correctly when plugging them into the MB and Drive.
ALSO, a small jumper at the back of the Drive may have to be moved to another set of pins.
Alot can be learned from Maxtor website.
I do not know about ATAPI drives.
