i bought a IDE to sata converter. it plugges into your ide port on motherboard or onto your harddrive and it creates 2 sata ports. and i plugged it staight into the IDE port on my motherboard then i plugged the 4 pin floppy power cable into it. then i plugged in a third harddrive into the converter and it works fine detects all 3 harddrives. so then i bought a sata dvd rom and plugged it into the converter. so now i have 3 harddrives (2 into motherboard and 1 into converter) and 1 dvd rom that is plugged into converter. but doesnt work. it either only detects 2 harddrives the ones in the motherboard or 3 harddrives or 2 harddrives and dvd rom it doesnt detect all 3 harddrives + dvd rom at once. pls help
