I just bought a SAMSUNG sh-202 super writer so I that can burn dual layered dvds. After I unplugged the old one and plugged in this one the D: and E: drives are missing! I noticed this after roxio said that I had no drive selected. I tried all this bs with deleting registry info and installing nero but none of that crap worked. I do not know what is wrong but I will answer any questions needed to diagnose the problem. Please Help!!! This is pissing me off!
