I've been asking for a lot of help lately and figured I'd post what went wrong in hope to help some other people. My main problem was that immediately or shortly after I began a burning cycle I would receive an I/O error and some type of Semaphore timeout. It turns out that the combination of my OS (windows XP) and USB 2.0 was not compatible with my external burner. Maybe everyone here knew this, but I had to do a lot of searching to find this… Sure enough, I successfully burned a movie and CD on my parent’s computer which is USB 1, I have USB 2. I tried the same exact burns on the computer in my room and got the error. So to make a long story short after a week of trying to figure out what the hell was going on, I took back my external mad dog burner and plan on getting an internal sometime this week. Any suggestions? I’m looking at… http://www.newegg.com/Product/Product.asp?Item=N82E16827151136 It’s the same as the mad dog external except it’s less than half price and internal.
