My Vista-based PC contains two disk drives, one for Windows and programs, the other for my data. A couple of weeks ago I replaced the data drive with a new 1TB Samsung Spinpoint disk. I have just noticed that it is running in PIO mode 4 instead of UDMA mode 5, and the DMA box in Device Manager is grayed out.

I'm guessing that this is causing me to derive less than optimal performance from the drive. Is that correct, and if so, is there anything I can do about it?
