[QUOTE=sicknero;2545412]IDE ribbon cables, are they identical for cd-dvd drives and hard drives? Can the one be used for the other?[/QUOTE] Yes, the same IDE cables can be used for harddrives and optical drives.
There are however two kinds, the old 40-wire cables, and the newer 80-wire cables. The newer cables can be used with all IDE/PATA harddrives and IDE/PATA optical drives, but the older 40-wire cables may slow down newer drives or sometimes even make newer drives fail to operate properly.
