I am replacing my ide dvd writer with a sata one. However the ribbon like cable on the ide dvd writer is connected to (a) the dvd writer itself,(b) the hard disk drive and (c) the motherboard. However the sata cable that came with the new dvd writer has only 2 connectors (one for the writer itself and one for the motherboard. Do I need therefore not need to connect it to the hard disk drive? or must I purchase another cable? Your help is much appreciated. Thank you in anticipation. Louis.....
