having trouble finding one of these however i have no trouble finding a new combo drive. the combo drive is 16x10x40. will this work? the drive it's replacing is a 8x8x24 and burns dvd's at 1x. as long as this thing will read dvd's and burn cd's i can live without the burning of dvd's. any opinions? i think i can figure out what the 16x10x40 means but can someone translate it for me?
