Well I had a problem similiar and maybe my advice can help you. First of all here is the problem I had. I have a DVD-RAM drive. It couldnt read DVD Videos or DVD Games.
It could however read regular CD's. After a bit of frustration I talked to one of my buddies and found that he said it was a problem with the laser reading your DVD's.
My Lenovo Y500 series is having a problem in CD DVD Rw, my notebook is is just 2 - years older. It is making so much of noise after inserting dvd or CD And also not reading CD, s just show blank on the drive.
He told me to get a lens cleaner CD. I didnt have one so I went to my bathroom grabbed a cue tip and some rubbing alcohol and dipped the cue tip in it. I dabbed it a bit so it wasnt soaking wet with the alcohol. I then opened my dvd ram drive's trap and rubbed the laser lens with the cue tip. I inserted the dvd disk and it worked.
Lenovo Cd Drive Not Reading Windows 7
All you need is a cue tip and rubbing alcohol and you win. I hope this helped. This is not always a lens' problem.Case in point: I re-installed Windows-XP for a friend, plus I installed Windows-7 for him on that same machine on another partition.Result:- the DVD optical drive reads both DVD's and CD's on Windows-XP &- the DVD optical drive reads only DVD's and not CD's on Windows-7 on that same machine on another partition.I would say like AARRGGHHH:It looks like an IDE-0 Master to IDE-1 Slave problem, since there is nothing wrong with the lens' themselves.
Either that or the fact that it's missing drivers when working with Windows-7.
