Well, I have been having all of these problems with my computer and had to go through this whole ganza migel (big thing) to try to get it working. Well my CDRW still wasnt working, so I contacted Micron and they sent me a new one. Thing is, I have a 4x sony and they sent me a 8x Nec as a replacement. While I am not sure if the quality of the NEC is comparable to the sony, but I figure it is great that the CDRW is twice as fast. Anyone have any clue about the comparable quality.
