The DVD drive was not recognized as a DVD unit by the operating system. It would function as a CD drive but even with aftermarket software installed would not read a DVD or even recognize that one was in the drive. The hardware is so old that HP's website doesn't even have information on it or drivers anymore. Tried to reinstall Windows to the 1TB hard drive and the system would not see that drive at all. The "tech support" person seemed to be reading from a script and didn't have any idea at all how to help. After three tries they told me to box it up and send it back.
