Ananaki- Now, Right click on my compuer, select "Properties", go to Hardware tab, and click on device manager. your drive will be listed under "DVD/CD-ROM drives." When you find it, right click and select properties. Look for something along the lines of "transfer mode." Make sure it is set to DMA and not PIO. if there is not an option for the transfer mode, go to your IDE controller. Right click the primary or secondary chanel and select properties and look for the same thing about the drive and DMA/PIO modes.
