i have a dell optiplex gxp1 mid tower w/ xp family o.s. i installed a sony dvd rom drive awhile back & had alot of trouble setting jumpers & connecting ide cables correcly. finnally got it working. but when i go into device manager & select drives it only shows dvd & not cd-rw drive. & when i got into my computer it shows d drive & e drive dvd drive. when i load a cd in the cd-rw to play music nothing happens. & when i load one in the dvd drive its plays. it also plays dvds great. i'm just wondering why it does'nt show in device manager.
