I bought this over a month ago and it seems to have one huge problem. Some times when a blank CD is inserted the computer will say d drive inassessable or error when I click on it . I have Windows XP with a Pentium 4 process. It only does this once in a while. Which irritates the heck out of me:a. It will open all already written DVD's and CD's. But if I try to add to CD with space on it, it acts like it can not. Or if I put a blank CD in it, it acts like the drive is not working. It happen today after my computer had a hiccup. (froze up and took forever to unlock.) Then after I checked all the connections and programs on the computer. The drive started working again. I thought maybe the driver I have for my D drive is to old? The computer is a 04-05 Gateway Model and the Lite On is Oct 08. It is a internal DVD/CD writer with light scribe and smart erase. All forms of CD _ +R and DVD _+ R ares suppose to work in it.
