I'm wondering if anyone can help me with this little problem, or at least give me an idea as to what is going on so I can figure it out somehow. For some reason, my Harddrive will not run in DMA mode in XP. I still have ME on this system also, and appears to be running in DMA mode there. The only option within XP for the IDE controller is Auto Detect and PIO Only. Checked the BIOS, and it is set to Auto there also, and both my CD Drives on IDE2 are running in DMA. Now, I'm pretty good when it comes to computers, and can usually fix most problems that appear (format usually does the trick), but when it comes to HD settings and features (as well as all this new RAM) I'm one lost guy. I've tried searching around on the net, but didn't come accross anything too helpful, and have just survived with slightly less than optimal perormance, but I got my TV Tuner back recently, and it keeps warning me about performance issues in this mode and magically figures out some way to drop over 400% of the frames when capturing sometimes. Someone suggested to me that I update the drivers... but wasn't very specific which drivers those are (but then again he also suggested, very sarcasticly, that PIO was better). I have an ABit BX6 v2 motherboard, Seagate ST328040A (28.6GB) Drive, running WindowsXP Pro. Should I be looking at drivers, cables, settings, Bios upgrade, format?
