i have a TSSTcorp CD/DVDW TS-H552B. the problem is whenever i want to burn a cd, i insert a blank cd, but it won't read it, it will ask to insert a blank cd. i tried burning it through nero and windows media player, but it doesn't work. i reinstalled the drivers, and even did a system recovery, but it still doesn't work. it burned two cds, then it stopped working. i haved tried cd-rws cd-rs of different brands, but it doesn't work. any advise????
