I am having similar issues with an Intel 845 based board. It sounds
like your disks are running in PIO rather than in UDMA mode.

hdparm -d1 /dev/sdX
substituting the actual device names for each drive?
I was unable to remotely fix mine, but plan to visit the machine soon
and fiddle with bios settings to see if I can get the drives out of PIO
