Try disabling DMA on that drive (you might have to disable it on more than just that drive, due to shortcomings in Windows' drivers, AFAICS). I have a friend who has a VIA-chipset board with an Afreey drive and he has to disable DMA in order to get it to function without errors. There were also aome issues with the VIA 4-in-1 drivers. I think I had to not install them to even get that marginal hack to work.
