I used to have 2x200GB in RAID1 on the silicon image controller, for some reason after a few days since I got my PC things started slowing down to a crawl: HD tach gave me a transfer rate for my raid of 2 megabytes/sec! (and 30msec seek).
I kind of got fed up with it and decided to just go with a single drive and just backup to the second occasionally (probably an even better idea) so I moved an HD to one of the 'normal' SATA ports and left the other disconnected.
Currently I have a DVD-RW on IDE0 as a master, and my drive on SATA2. Doing an HDtach gives my transfer rate at 13MB/sec with 100% cpu which is a dead giveaway of dma being 'off'. All of my entries in the device manager are 'dma if allowed' and the one I *think* the SATA HD is in is set to PIO.
How do I enable DMA for my HD? For some reason I also always thought that SATA wouldn't be shown together with the other IDE controllers, not to mention that I thought it would use the NVIDIA driver rather than the MS one (right clicking on my HD in the device manager shows a MS driver).
I am really going nuts here, been trying to get this to work for several hours but no dice: could somebody please give me a hand? thanks in advance.
