i have only 1 cd drive and its a burner. but very slow afriend gave me an old acer cd-rom but i dont know if i can add it to my system i thought if i could it would save me some time . 2 drives are faster than 1 . not sure but i thought i could burn disc to disc instead of disc to memory and then to disc.i'm using xp os and the old cd-rom is an 1996 acer cd-912e. could some one please help?
