I don't know about the "b" part. I have a Samsung sw-224. As I recall I just hooked it up and installed roxio.
Page 8 of user manual says no additional driver required for win(versions)as the default windows driver is used. With that as a starting point, I'd guess you'd want to work through things that the other participants would tell you to do to check for a properly installed device.
Three important ones I had to deal with were the cable, the master/slave settings and using the second ide connector on the motherboard. I don't remember what they were, but I had some problems when I tried to use it on the same cable with the hard drive. Then I went to the second ide port and tried to be frugal and save the new cable that came with the drive and use a used one that I had lying around. Wrong!
It was bad. After I got that checked out, the cdrw still wasnt working and the guy that sold me the computer had to remind me about slave/master settings.
Those things fixed my problems.
