Someone please correct > me if I'm wrong. 33MB/sec on UDMA 100 is pretty flashy performance. 36 is the best I have seen. If you want everything out of your notebook, download drakopt-1.01-0.86mdk.noarch.rpm from cooker. Install with rpm -ivh and run it as root. Just run it. The current version works with 8.0. It does not yet have the tradeoff algorithm that picks the best signal/noise ratio or the processing of stderr to detect the case when some drives interact on the same IDE channel and to afvise the user to separate them, but the basic functionality of checking options is there. Often you will get better performance at UDMA 66 or 33 than at 100 (Yes, noise and retries), and it does catch that case. It may take 30 minutes to do all the tests.
