The above is what I got for my DJNA connected to HPT366. So
indeed your disks are running in the ancient PIO mode, which is
about as slow as slow can be. The likely cause? The "use DMA
by default when available" kernel option is turned off, most
likely because it would cause some trouble for some (old) VIA
chipsets. And the solution?
# hdparm -d -X66 /dev/hde /dev/hdf
Should do the trick.
