DMA Mode
in [Windows XP]
|
From: Rhino on 26 May 2010 19:14 I'm using Windows with XP SP2 on a nearly new computer (18 months old). My CD/DVD burning software is Nero OEM 6.3.1.26. (InCD is 4.2.12.1.) Whenever I attempt to burn a new CD or DVD, I get a message from Nero DMA Manager saying "This application has detected that your drive is not in DMA (direct memory access) mode. To improve your system performance we suggest you to enable DMA for all drives. Do you wish to run Nero DMA Manager to enable DMA mode right now?" I have clicked OK and rebooted (after it was done) on several occasions but I keep getting this message. I've checked Device Manager and found that both Primary IDE Channels and both Secondary IDE Channels indicate a Transfer Mode of "DMA if available" for both devices in their Advanced Settings. 1. It looks as if the settings are correct so why am I still getting the message? 2. Is it possible that I am actually using DMA despite the message? How could I be sure? 3. Is it possible that a CD/DVD burner manufactured within the last couple of years would _not_ support DMA? I thought that only very old drives didn't necessarily handle DMA. What would I need to know about the device to determine if it supports DMA? The burner is a Lite-on DH-20A4H 20x DVDRW. I'd like to get the DMA mode working if it isn't, assuming that it will actually speed up the burning process. If it doesn't speed up burning or have some other major benefit, then I can live with it the way it is ;-) Suggestions? -- Rhino

This is the usual method of fixing your problem. Windows XP changes the mode to PIO rather than DMA if there ever is an error on the drive whether it is currently recording errors or not. Jim

Many devices require a jumper to be set in order to utilize DMA ... check the manufacturer's data sheet for the device.

I'll get back to you if they don't pan out but I'm optimistic that one of these will solve the problem. -- Rhino |
