Correct model designation is UJ-840D. OEM drive for laptops. No driver is required. Windows XP provides native support that allows this drive to read a data or music disk. Compatible dvd decoding software (like WinDVD or PowerDVD) provides the support that allows it to read a dvd disk.

If your problem is non-detection, CD/DVD issues are often helped by the "Delete upper and lower filters" fix:
