First of all I must thank KENB, for helping me the last time I asked for help. I don't know if this is for you KENB? But here goes. Yesterday morning I was using both my external DVD burner and player. Burner is a LITEON and player is a compact disc re-writable dvd rom. Come yesterday afternoon, when I wanted to use them again, my computer just would not recognize both! There is always a symbol C or D but nothing. I tried the "A NEW DEVICE" from 1 to 0, but still no good. Does anyone know what happened and can it be fixed please?
