Just plug it in, will work fine. They are backward compatible.
You use a SATA cable
Its called Serial Advanced Technology Attachment/SATA
It doesn't matter which side goes where, but for this example the HDD side goes to your DVD drive, and then the other end plugs into your motherboard.ty so much for ur help! ur very smart!
one last question tho on the other side of my cable there's HDD so i connect the other side to my hard drive then ?? or motherboard??
One device on each cable. If you have a SATA harddrive and a SATA DVD drive you use a cable on each, then plug them into the SATA ports on the motherboard. You will need two cables.
