i have two dvdrw's and i also have some virtal cdrom drives, no mater what type of disk i put in any drive my system not seeing the disk. when i dont have a disk in my dvdrw, if you look at it in my computer, it shows as a dvd-rw, but if i put any disk in the drive, dvd or cd, burned or retail, the system shows the drive as a "cd drive", and if i try to access it i get an error saying that the disk is corrupt, the same goes for my virtual drives.
the really odd thing is that if i put a dvd in the drive ,,, i still cant get to it from my computer, but "power dvd" can still play the dvd. this leads me to believe my drives are fine
i put the drives in an other system and they work fine, i tried new drives in this system and still the same problem.
also when i put a disk in the drive and take the properties of the drive, it shows the files system of the disk as "raw" and not cdfs
