I have two 3550’s in one computer and two 2510’s in another. Besides the fact that one of the 2510 trays has problems opening and closing, they both still read and burn great. My 3550’s on the other hand are less than a year old and are acting up lately. While everyone seems to have problems burning or reading a burned disc with them, mine do both of those great. My problem started as one of the drives struggling to read a master copy of some movies and now reads very few at all. Says no disc in drive. The other went from reading fine to not reading a master copy of any movie at all. Anyone have a clue as to why niether one will read a master version of any movie, but read everything else fine and still burn anything great? I have tried several different firmwares and nothing has changed.
Thanks in advance
