DVD Drive DMA Reset to PIO

[Randa]

While using DVDFab HD Decrypter I recieved a read error. I tried again and discovered that the transfer rate was much slower. I then discovered that Under System, Device Manager, the transfer rate for the drive had been reset to PIO. I tried to reset it and although I have set it to DMA if applicable the current transfer rate is still showing PIO. I even tried Nero DMA manager to reset it and restarted, but still it shows current transter rate PIO. How do I correct it. I am using Windows XP SP2.

Hi!

In the Device Manager (via the Control Panel>>System>>Hardware>>Device Manager), you simply have to remove the applicable IDE channel (Click on "IDE...Controllers") and let your computer reset it to DMA as follows:
Right click on the pertinent channel in Device Manager
Click on uninstall
Reboot
After rebooting go back to Device Manager and change the setting to "DMA if available"...

I thank you for your speedy and informative reply. I went to microsoft to try to figure out how to fix this issue and their 5 page document detailed substantial registry key changes which needed to be done. I have followed your instructions and it appears to have worked because upon reboot I could see that the transfer rate was already put back to DMA Mode 2. Is this uninstall and reboot all that is needed to fix the issue, or are there really registry key still needing to be edited?
Thanks for all your assistance

That actually removes all of the associated registry keys and recreates them on reinstall. So yeah, quick and simple.
