Keep DMA enabled

I am having problems with DMA being disabled by something on my DVD burner.
The problem with this is that it causes all sorts of upsets when burning
DVDs and causes the DVDs to be very difficult if not impossible to be read.
It is relatively easy to reenable DMA for the drive, but I am wasting DVDs
by burning and then realising that DMA needed to be enabled again, resulting
in another dud DVD.

Is there any software which will make sure that my drives are DMA enabled at
startup, or perhaps something which will ensure that DMA is enabled before i
burn a DVD with Nero (not freeware, i know).

Thanks.

Which Operating System are you using? What version of Nero? What Brand
and Model is the DVD Drive?
 
I had controller errors with my DVD drive (saw them in the win2k system
log), and learned that turning off UDMA in the BIOS fixed it; it's now
set to PIO4. But the DMA setting in Windows is on, and the speed is
much better than it was before. I thought maybe your IDE controller
driver was turning it off because of some problem like mine. I can't
imagine why an application would turn DMA off. You shouldn't need to
manually turn it on after each boot.

Make sure you have an 80-wire IDE cable (for UDMA). And maybe the drive
wants to be master device on the channel.
