Checking that box only enables DMA mode, which speeds up drive performance under Windows. It's not really the same thing as using hard drives and controllers that conform to the newer ATA66 specification. If you're not using 1) an ATA66 hard drive, 2) an ATA66 motherboard chipset or add-on drive controller, and 3) an 80-wire IDE cable, you won't get any performance increase. And to tell you the truth, there really isn't a huge performance difference between the older ATA33 spec (if that's what your hardware is) and ATA66, all other things being equal.
If Windows isn't letting you enable DMA on your hard drive, it's probably one of a few things: it's either an old hard drive, an old motherboard chipset, or (if the other stuff is new-ish) you don't have the latest and greatest chipset drivers installed.
You didn't specify what model hard drive it was, or what motherboard you're using, so that's all I can really help you with at this point. Post again with this info and maybe I or someone else here can help you out further.
