It sounds to me like plan9 doesn't know about the quirks of
your IDE controller, even though it obviously thinks it does.

You could try turning off disk i/o DMA just in case that helps,
DMA seems to be the quirkest area in the IDE interface.

	echo 'dma off' > /dev/sd00/ctl

Unfortunately this will have a significant performance hit but
if it works reliably then you could start looking at the datasheets
for your chipset to try to bugfix it.
