UDMA

Wouldn’t you know it. DMA is not enabled in a windows operating system unless explicitly invoked for a particular drive. So my fancy ATA100 HD I bought a year ago has gained me exactly jack squat until tonight when I checked the little DMA box under its properties.

If I hadn’t been trying to capture some scenes from my dv camcorder (and failing), I may have never realized I was running at a whopping 2 MB/s… checking that box increased it well over an order of magnitude.

    There should have been something about UDMA enabling under Windows in the manual or literature that came with the drive. Knowing the quality of some of this literature, though…maybe not.

    I’m a friend of Rollin. That’s why SCSI rules. If only it weren’t so dang expensive…
