This solved my problem,
This review is from: IDE to SATA Converter (Connect IDE Drive to SATA Motherboard) (Electronics)My computer wouldn't play DVDs smoothly (i tried everything i could about enabling the DMA, but nothing would work)neither DVD drives (master and slave) would work properly through the IDE connection, so i thought i'd try this,and it worked!
My DVD drive works so much faster than before.I should have done this ages ago.
Fantastic bit of kit,and easy to fit too.
I would have bought another but i've replaced the other drive with a SATA DVD drive.
