I'am new to this forum and i will be very much grateful for any help, so here is my, problem. My dvd burner reads all blank media as a cd-r,also I've tried to uninstalling the ata controllers witch i've seen on another topic. when I go to properties on the burner it shows that it full of memories and no disk space, also my dvd rom shows the same thing, i even did a system restore but that didn't help. Any respones will be appreciated. I forgot but it is a HL-DT-ST DVD+-RW GSA-H21N running on windows XP.
