DVD Drive keeps reverting back to PIO Mode

Problem

Despite changing the IDE controllers back to DMA mode (as mentioned in this previous article), they keep reverting back to PIO mode.

Cause

Normally the system will detect 6 cumulative CRC errors before switching the channel back into PIO mode.

Solution

The attached tool tells the system to reset the counter on success so it then takes 6 consecutive CRC errors on a channel before it will drop to PIO mode.

1. Change the IDE controllers back to DMA.
2. Download the PIO Counter Reset tool.
3. Run the program. You will not see any prompts or messages. Just make sure that you opened it.
