After my iOmega backup drive failed recently, I had to go out and get a new one. Since I’m trying to save some money I decided to go for a simple (USB only) Western Digital drive.
After plugging it in, it greeted me with a “virtual CD” drive with some additional software. Since I’m not going to use it, I was searching for a way to disable that. I found this page on their site. The VCD Manager lets you deactivate the extra drive (or reactivate it if you really need it). And while you’re on that site, you might want to check out their firmware update too.
Hope this helps
