If you are still having issues with any optical drive ( cd, dvd, blu ray etc ) type computer drive then you can try and install the latest motherboard drivers for your make and model of motherboard ( Sometimes this is also known as the chipset drivers ) to obtain these you will need to go to your motherboard manufacturers website.
To establish what motherboard you have you can use a few utilities.
Namely SIW, Everest ( I would suggest home edition as its free and the latest home edition was version 2.20 ) or belarc.

Also as a last resort check the optical drive manufacturers website for a firmware update for your optical drive - if they do then it is vital to read the read me file to see what functionality it adds or what it does and also how to apply the firmware update and follow those instructions to a T.
Ensuring that you do not turn your computer off during the firmware update as if the power goes off whilst you are in the middle of the firmware update it will brick the optical drive rendering it useless !!
