some notes:

* in case you can not get your hdd running with udma under 2.2.x ,
there is a possibility that the IDE controller is not supported fully in
kernel.

In my case, Intel triton II + WD caviar 6.4 gb
did not worked well until I switched to 2.3.41 (it was _long_ time ago)
and enabled Triton and Triton tuning in kernel.

* in case you are after getting the most out of disk, note that
IDE channel is not capable of running 2 devices simultaneously. Thus,
splitting all slow, or high latency devices on one secondary channel is
beneficial.

* hdparm can be used as hdd benchmarking tools with -T and -t switches.
Note, however, that throuput rates reported by hdparm has little in
common with real life performace. Having said that, you can compare
hdparm -Tt results
when you are applying optimisations, just to be sure that controller is
aware of your actions.


* There is Ultra-DMA mini HOWTO.
