DVD burner is suddenly burning slow? Slow DVD / CD burning driving you crazy? Having a bit of a burning issue? (video, data, isos, anything). Drive used to work fine but starting to take a long time to burn? Every burning program having the same problem? The burn always succeeds, but always takes a long time? Well this guide will show a solution to help fix that.
What’s the main cause?
One of the things that causes your drive to burn slow all of a sudden is that you previously had put in a dirty or scratched disk & your drive light was flashing on & off for a while trying to read it before you ejected it. When your drive accesses a bad disk like that for a period of time it can go into PIO mode which is slow. DMA mode is faster than PIO mode.
As Microsoft states: Windows will turn off DMA mode for a burner after encountering errors during data transfer operations. If more that six DMA transfer timeouts occur, Windows will turn off DMA and use only PIO mode on that device.
What’s DMA mode?
Direct memory access (DMA) is a feature of modern computers and microprocessors that allows certain hardware subsystems within the computer to access system memory for reading and/or writing independently of the central processing unit.
What’s PIO mode?
Programmed input/output (PIO) is a method of transferring data between the CPU and a peripheral such as a network adapter or an ATA storage device. In general, programmed I/O happens when software running on the CPU uses instructions that access I/O address space to perform data transfers to or from an I/O device.
INSTRUCTIONS
- Go to Control Panel>System>Hardware>Device Manager>IDE ATA/ATAPI controllers.
- 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.
- 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.
- 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 & burn your files in peace.

damn, my prayers been answered, thank you!!!!!!!!!!!!
This is an awesome way to troubleshoot my slow burning dvd drive. I just change back from PIO to DMA mode, my burn process flies with no body business.
@yloon: Glad my video helped and your burn process is flying!
Thank you!! This solved my sister’s computer problem! It works like a charm. Instead of burning at .070x It’s burning at around 12x again! \^.^/
Thanks a bunch, solved a very frustrating problem for me.
Been burning DVDS for many months with the same setup then suddenly I’m getting 1x burn speeds and the drive light flashes slowly rather than staying on steady as it always has.
I had no idea that windows could or would change the transfer mode and leave it that way.
Thank you! I found that doing the uninstall was the best and easiest way to do this!
my god your tips saved me and I will book mark your page ,thank you very much god bless you.
@qsxwdc: Glad I could help, thanks for leaving feedback
Thank you! It worked. My drive is a lot faster now.
How to make it so it never happens again, no matter how many errors? Microsoft’s “fix” doesn’t work (and is supposedly included in WinXP SP2 anyway).

Thanks for supplying such a helpful bit of information for those of us that are not as computer savvy.
Thank you , information very helpful!!!

Drives Hp and Lg
Thanks for the info.
Your fix worked just as described.
Cheers
This had happened to me on my desktop before and I found the fix for it. This time, it happened on my laptop burner and I’d forgotten the technique (blush) to fix it - but fortunately found your site. Thanks for the refresher course.
Now … the big unanswered question(s). First, what is it that causes a the IDE channel to revert to PIO mode? And secondly, is there a way to prevent it from happening in the future - before it happens?
Thanks again.
@AlecWest: Glad I could help
This happens especially when you put a bad / dirty disc in and it keeps trying to access it, so what happens is it times out and then goes into the PIO slow burning mode.
To prevent this, make sure the discs are clean
Hi JGG,
You haven’t answered bk’s question? any idea? a have the same issue!!!
@bk & @JH: I believe the issue of playing things from hard drive and its still slow you may need to defragment your hard drive and make sure it has more than 20% free before you do. That may be why things are sluggish when playing from it, if its not that then maybe some more ram, Please give me computer specifications.
THANK YOU, YOU HAVE SAVED ME FROM A LOT OF TROUBLE, FROM BURNING DVD’S MANY THANKS
THANK YOU, YOU HAVE SAVED ME FROM A LOT OF TROUBLE, FROM BURNING DVD’S MANY THANKS
u r awesome!
Magnificent ! I would like to insert a illustration to illustate your great article, but I don’t understand how to do ? Can someone assist me ?
My settings are already set at DMA. This has not helped at all. My Windows Media Player is taking ages to burn CD’s. About 10 minutes to even prepare and analyze one song. I need some help on this immediately… Help me!!
@JD: You need to uninstall your DVD drive as shown in the video and it will work, not just setting to DMA, Please watch full video
