Tenchusatsu,

In the Advanced Settings, you can change the transfer mode from "DMA if available" to "PIO only."

Thanks for the reminder. I remember doing it some time ago, but I completely forgot about it. These days, Windows seems to default disk drives to "DMA if available".

It has been a few years when I was helping a friend with a project, when we realized that his IDE disk transfers alone consumed upwards of 50% of CPU utilization.
