Just a heads up about Aopen CDRW's.
Avoid them like the plaque. We have only had luck with the 24x10x32x. The 12x and the 40x are pure garbage. Several have lost their ability to burn within 30 days. The RMA service is great, but the product you get back is just as crappy as what you send in.
I plan to use these forums to let other builders know about some of the garbage out there on the market, like Western Digital.
Have a Grate day.
