Did you ever get the dreaded “Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)” message in your Device Manager for your DVD/CD-ROM drive?
This happened to a computer here at our office, and it did this for both the internal drive and for an external USB drive that we hooked up to it as well.
Well, to solve the problem, we found this link and ran a neat little automated program from Microsoft that went in and fixed up the drivers for both the internal and external drives.
Your CD or DVD drive can’t read or write media
Very cool. This was way easier than some of the other solutions that we were seeing.
