Hi I want add an additional internal hard disk and i have ATA type currently. The problem is connecting the data cable; i have two sockets on my motherboard only - both in use. One cable goes to the current disk and one of the cd drives, the other goes to the other cd drive i guess. So i have no free sockets (i have 2 cables but only one has the midway connector but is in use as described). So is the solution to replace the cable that doesnt have a midway connector with a cables that does have one?
