Dvd writer

So i have been having some problems with my samsung dvd writer whenever i tried copying some file from a dvd it takeslike 10 minutes and to write a dvd at 8X takes 45 minutes.But after researching for a while i found out it was a problem with my IDE Channel configuration.The dvd drive was set in PIO mode instead of DMA Mode.So i tried changing it to DMA the easy way but it did not work,so i uninstalled and reinstalled the primary IDE channel.Now the writer is working perfectly.If you want to do this go to My Computer-Properties-Hardware Tab-device Manager.You can find everything i talked about there.
