1st welcome to CDFreaks
2nd If you are running win95 or later you don't need any "drivers" as such for 812S to make it work.
You will need software if you wish to burn CD's or DVD's and I'm sorry to say if the drive didn't come with any software when you purchased it, you will now have to buy some. :sad:
Most people seem to use Nero, as I do, you can download a demo version from www.nero.com/en
