Hello, I'm new here. My DVD drive has been working at full speed(16x) for the past two years but suddenly it's gotten really slow. It used to take around 8 minutes to burn a 4.0gb disc but now it takes about 2.5 hours. I tried to figure out what was wrong and all I found out was something about the disc drive being in PIO mode instead of DMA, which is causing the slowdown. So i went into the Device Manager and tried to change it back to DMA, but I can't really do anything. The only two options are "DMA if available" and "PIO only". Anybody know how I can change the settings back to DMA? Or if this isn't the problem, can anyone suggest any other things that would return my dvd burner to full speed? Thank you!
