I have tried all the threads and nothing is working for me. I have been working very hard to get my cd drive to appear in my computer since yesterday. On this morning I cut my computer on and it recognized the cd drive but as soon as I restarted my computer over it disappeared. Does anybody have anymore solutions to getting my drive to work every time I boot my system up. I mean every time I restart my computer I see the light flashing on the drive and I can hit the eject and it comes open but as soon as my system boots all the way up it stops.
