Nothing special is needed to play a data or music disk.... Windows XP provides native (eg: built-in) support that allows it to read a data or music disk. However, to play a dvd disk, you must have a MPEG-2 decoder software installed (like VLC Player which is free), Cyberlink's PowerDVD, or Intervideo's WinDVD. There are more than a dozen other dvd decoder software's available as well.
Are you saying that the name of the drive (in Device Manager) does not match the actual drive name or something else? Has it ever showed the correct name in the past? What I need to know is this: Is the drive listed in "My Computer" and does the drive icon in Device Manager show any flags which represents a problem? If you can answer these questions, I might be able to help further.
If you want to try a registry edit (to solve the problem of drive is not listed in My Computer), then read any of my other posts in this forum and you will find instructions on how to do so.
Also, you might have the wrong IDE driver installed for the drives controller adapter. Try un-installing the IDE adapter driver (in Device Manager) and without restarting the computer, un-install all drives listed under CD/DVD Drives section of Device Manager. Then reboot and allow Windows to re-install all the hardware devices. It does so without user intervention... all you have to do is reboot the pc after un-installing those listed devices. After a reboot, check to see if everything is ok in My Computer and Device Manager.
And fyi, internal drives do not have FireWire interfaces... this particular drive has an E-IDE interface, not a Firewire / 1394 interface.
