1. Go to Control Panel>System>Hardware>Device Manager>IDE ATA/ATAPI controllers.
2. From there, right click on each of the channels and choose ‘Properties>Advanced Settings’. All drives should be DMA mode. The ‘Current Transfer Mode’ for Hard drives is usually DMA 4-6 and DVD burners DMA 2-4, DVD ROMs usually DMA. If you see any in PIO mode, that can slow things down.
3. If you find a PIO mode drive, changing them back may be easy or complicated. First see if you can change them in that window using the drop down menu.
4. If not, uninstall the channel the drive is on and let the OS reinstall it. This will usually take a reboot. This will not damage any files on the computer. Now your burner should be back to normal. Check the drive settings again when computer restarts.
