I just bought a new LG IDE GH22NP20 internal DVD writer. Installed it as usual, and suddenly it just won't appear on my drive list. I changed the jumper (CS,MA,SL) still it doesn't work.
If it's happens to you, try this link. I did it any suddenly it worked perfectly!
Restore DVD/CD drives in explorer (download the file, run it. Restart your PC)
