Hi raider4123,
The Western Digital Scorpio (WD2500BEVS) doesn't come with a driver, but I have an idea that perhaps you may have a pin setting wrong, making the drive not recongizeable. Here is the information on setting the pin on the back'
If that doesn't seem to solve the problem, then I'd run the WD Lifeguard software, that will detect any problems and correct them for you. You can find that software
HERE.
Good Luck,
And don't forget to leave a rating.
Thanks
Mark
