superdrive logicboard port fried

heres an update to my original question about a superdrive logicboard port being fried. i finally got the macbook and when the wife let me have it for a minute i did some checking to see if i was told correctly. now i was told by the original owner that he had a professional check the computer and said the port on the logic board was fried for the superdrive. so now i get it and when it boots up, the superdrive starts up and makes the normal drive sounds. and it shows up on the system report. now, it hasn't read a dvd or anything yet, it sucks it in, makes some normal sounds, then abnormal sounds then spits it out. no error messages or anything. now, its my understanding that if the port is fried, the superdrive shouldn't work or even show up in anything. am i safe to assume this? i personally don't care if the superdrive doesn't work, ill replace it with a bracket and put a hard drive or ssd there like i did my pro. best upgrade ever. thanks all.
