I have fixed this problem before but honestly have no clue what I did or why it broke again. My cd/dvd burner is not recognizing my cd's. They are the same brand I've been using so that's not the problem. But everytime I go to burn a cd it tells me to insert a blank disk into the cd drive (F) when there is already one in there. It can read cds/dvds but won't recognize blank ones. I have tried uninstalling the hardware and restarting my computer to let it find the new hardware but that didn't work either. What the heck is going on? I'm literally seconds away from just throwing the whole thing out the window!
