I have a combo Sony CRX300E 48x 24x 48x 16x, and I was worried about overburn. I have done some research and I think that my drive is actually a Lite-On LTC-48161H, but I'm not sure.
According to the great review on Lite-On LTC-48161H: http://www.cdfreaks.com/article/123/7 it says that drive is able to overburn 99 minutes cd's without any damage.
Because I'm not sure if my Sony CRX300E is exactly the same as Lite-On LTC-48161H.
My main concern is in the past I had a Samsung SM-348B Combo 48x 24x 48x 16x that was unable to read/write any cd, just after I had done an overburn on a 99 min disc (it was not the first overburn in that drive).
So if you give some advice I will appreciate.
