Why are my CD-RW/DVD drives on the 'PIO' Mode??!?!?

[theNEOone]

I have selected "DMA if available" in the device manager settings, but the current setting listed is PIO. Why wouldn't DMA be available?

drive doesnt support dma maybe?

mine doesnt either

but just to be sure check in the bios itself
go into device properties and see if you can manually change between modes and if it sticks

either that or look on the www for information regarding if it can go dma or not

//edit
btw you are not losing much performance between pio4 and dma2
pio4 max is 16.6mb/s and that is most likely max of your drive

Your drive probably does support it. Many people have had problems with PIO in XP. If you have already set it to DMA if available and it is still detecting as PIO mode there are two things that you can try:
1. The bios is not reporting the drive's abilities correctly. Make sure it's on auto and if that doesn't work try to manually specify. Update your bios.
2. Delete both the primary and secondary ide controller from device manager. Reboot, redect. Set to DMA if available and reboot again. This usually does it.
