Pioneer DVR-K15RA not reading DVD's issue



I have a Acer laptop aspire 3000 that has a pioneer dvd/cdr burner drive model of drive is: DVR-K15RA FW 1.04 and I just replaced the original one because it was not reading dvd’s and cdr’s at all it was making like a grinding sound. So I got a used one off ebay and installed it and it reads regular cd’s fine but wont read dvd’s at all, I tried burned dvd’s, dvd movie and even my dvd pc games.

Anyone know whats the problem here is it a bad drive or is there a firmware that can fix it? Thanks.
