Was this post helpful ?OK I've fixed it .
I found that WHS has downgraded one of my drives to use PIO Transfer Mode (Device Manager -> IDE ATA/ATAPI COntrollers -> Secondary IDE Channel -> Proprties -> Advanced Settings). This apparently happens is Windows encounters errors on a drive. I used Device Manager to Uninstall the Secondary IDE Channel, then rebooted to force Windows to re-install the Secondary IDE Channel. Bingo! It is now operating under Ultra DMA 5 mode.
Now I just need to find out why it got downgraded in the first place. WHS is not showing any disk errors.

这个也是微软(忘了是不是美国论坛)论坛上搜到的,大家参考下。我最近更新过的硬件只有硬盘,所以觉得有一定道理。大家觉得如何?
