How to enable DMA? i can't find it by right clicking and click properties =(
This example if you are using an IDE channel (P-ATA type). You need to access Device Manager and look in the tree view for IDE channels. Open its Properties and enable Auto Detection option to let Windows to choose the supported DMA mode.
However, some ATA devices are so stubborn and crazy sometimes, causing Windows to drop to a lower mode (like PIO mode). This normally happens with CD/DVD drives which is causing slow access speed and jerkiness. There is a script below which will force Windows to recognize the ATA devices in DMA mode.
