Slave drives on ATAPI channels are often set to PIO mode by default, even if they are capable of modes such as UltraATA or DMA, which allow more efficient data transfers. This means CD/DVD burning, DVD playback, and other performance may suffer unnecessarily.

To fix this problem, in Windows 2000 or XP, open the System applet in the Control Panel and select Device Manager in the Hardware tab. Expand the IDE ATA/ATAPI controllers section and double click on the Primary IDE Channel. Choose Advanced Settings, and change the transfer mode for each drive to DMA if possible. Repeat this with the Secondary IDE Channel. For Windows 98 or Me, go to Device Manager, then Disk Drives | Hard disk properties and click the Settings tab. Click the DMA box. There's no harm done if a device can't handle DMA mode.

Looks like both my primary and secondary were already set to the DMA if possible.
