CRX300E5 (LTC-48161H) Last Resort

My sony combo drive was having problems reading and writing (inserting noise, not reading some prerecorded music discs, gradually got worse), upgraded to KYS2, reloaded all drivers, etc, pretty much useless now. I am going to go ahead and load in the firmware for LTC-48161H, but would like to know if there is anything else to try on this drive. It is only 1 1/2 years old, really has not gotten much use, is this death common? I have swapped out with a known good drive, works fine, so it is definitely the drive itself, not the computer or software. Can these be opened to clean the laser? I don’t think this is the problem as when it had problems reading, it was always the same track (ie would read 1-3 fine, but would get stuck on 4).
