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.
- 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.
Other ways to fix a slow burning DVD drive:
- Update its bios or firmware. You get these files from the manufacturers website.
- Close all other open programs & your anti virus or firewall program.
- Make sure drive(s) that hold what your burning has at least 14% free disk space.
- Defragment your hard drive(s).
