Query: Dissapointed in Sony!

I am dissapointed in Sony! Usually you can't go wrong. However,the drive just doesn't do what it claims. It will not write fasterthan 8x when burning files and 4x when going from CD toCD. Bufferunderruns are the norm and not the exception. When it didrun it was real noisy. I tried callingSony.................................................I waited longerthan this, and they hung up on me after 35 minutes waiting to talkwith them. This happened three times. That was enough. You have tostand behind your product...
