I've had an GSA 4160B for almost six months now, at first, it seemed to work fine, but lately, it can't seem to burn properly. IT woulda show read errors when I do a verification using Nero, but when I open the CD, all the files appear, but I can't actually run anything. I tried that SAME CD that wasn't working on my computer on my brothers computer and it worked fine. I even reformatted everything and reinstalled XP SP2 and it didn't make a difference. I've used Pine brand and Memorex brand CDs. Anyone have any suggestions??
