Summary: My CRW2100E drive worked pretty well for first few months. On around the 7th month, I started to experience some problems...the drive would not read/write CD's occassionaly. On the 8th month, the it failed completely. I do not burn alot of CD's. I burned around 80 CD's only during the lifespan of that drive. In the end, found out that the problem was with the laser unit of the drive....which was probably caused by the drive not being well-balanced.
