I put it back in the box to exchange it for a good one.
Just out of the box and it won't read CD's.
Windows 8, drive is TSSTcorp DVDWBD SN-406AB and device manager has no yellow flag. I ran the MS Fixit prog but it just said no readable cd in the drive. driver is latest available. I've tried installation cd's(Norton) and audio, but nothing works. Samsung help dept. got me to run 'recover' which just deleted all the stuff I have just spent a day installing.
Needless to say this is very frustrating when I have just paid nearly a grand for it and I can't even install antivirus.
