Hi, I had this problem a couple months ago, fixed it, and am now facing the same problem again. I have a Vaio, Windows 7 64. My CD/DVD player isn't reading any of my DVD-R cds. Whenever I put in a DVD-R cd, autoplay comes up and it asks to format the cd. I checked these DVDs and they work on other computers. They're all burned DVD with files on them. Before when this happened, I tried many different things. I... 1. Deleted upper/lower filters. -- Actually, I didn't have upper or lower filters to delete. 2. System restored 3. Deleted and updated drivers 4. Finally found a post talking about creating a new key in the regedit NoCDburning. After doing this, it started working. Fast forward three months later, my cd/dvd player won't read any of my DVD-R cds again... I did the same things all over again. 1. System restored 2. Deleted and updated/re-installed drivers 3. Ran Fixit 4. Looked for upper/lower filters -- not there 5. Tried looking at the NoCDburning thing again -- deleted and repeated the steps, and nothing is happening. I don't want to reboot my computer because I already did a month ago and it just takes way too much time for me to reboot everything all over again. I cleaned my CD player as well like most of you guys said before. I know my drive is still working as it worked before after I fixed it. I checked and the last time this happened was in June. Since then the only new things I installed/updated were CC Cleaner, Itunes, and some other programs.. I have Spybot as well. Can someone please, please, please help me?!? I've been looking for an answer everywhere and I'm running into the same answers. Thank you!
