Matshita DVD RAM UJ-875S

There are normally no drivers, other than those already present in the XP operating system, and in the device itself.
If you have lost the ability to access the DVD drive, try instructions below first.
In some proprietary systems such as Dell and others, there is firmware that must be installed for all of the features to operate. If you have somehow lost that firmware from your system, that might also cause a problem.
For example, go to the Dell website (or your manufacturer website) and look up the model of your computer, find the drivers.
Try re-installing the chipset drivers, and other motherboard drivers, if the solution below does not restore access to the drive.
For example, in a Dell computer, the motherboard features will not operate without those firmware drivers installed first.
