Device manager -> IDE ATAPI Controllers.

DMA if available.

delete/uninstall the ide channel that the drive is on in device manager then reboot!

The reason the drive has switched back to PIO mode is because the drive does not support DMA mode correctly. A possible alternative explanation is that your IDE cable is of low quality and is losing data (this is probably less likely).

This is a surprisingly common problem with CD-RW drives (my own TDK does the same) and is due to a bug in the drive's firmware. It is the prevalence of bugs such as this that is why Windows does not automatically enable DMA for optical drives.

The drive says it supports DMA, and windows believes it. If you enable DMA, then windows will attempt to use DMA - it will probably work, and you get fantastic transfer rates.

However, it is only a matter of time before the bug appears, and the drive starts losing data and malfunctioning. Windows is quick to spot this, and after about 10 fatal errors, it will give up and force the drive to PIO mode.

You can temporarily restore DMA mode by going to 'device manager' and uninstalling the IDE controller that the drive is connected to. This will cause windows to redetect the drive, and lose its error record.

The only way to fix it permanently is to replace your drive with one that fully supports DMA. You should, however, double check that you are using quality 80 core IDE cables and that they are in good condition before replacing your drive.
