'DMA' on Hard Drives
I could never figure why the DMA option would ever be used under Hard Drives. Now I know.
I was trying to transfer some AVI files from a 7200 RPM hard drive to a 5400 RPM hard drive. Halfway through a 100 MB transfer, my computer would freeze up.I tried this several times and each time it would completely freeze. It always worked before when going from the slower to the faster drive. I enabled DMA under the 5400 RPM hard drive and everything works beautifully now. |

Every time that I tried enabling DMA, a popup would say that this device may not work correctly , so I never attempted to do it. Besides, certain writers I have definitely will not work correctly if DMA is enabled on them. |

I've always used DMA on CDRW drives (and DVD drives).
I wrote a CD a couple weeks ago. It took over 15 minutes. I looked and saw the drive was using PIO instead of DMA. It had been a while since I had used it, so I hadn't noticed any problems. I enabled DMA and it is now taking around 2 1/2 minutes per CD. |
