	Erm... I was quite shocked to read that in the newer kernels,
hdparm doesn't produce incredible results, as the new IDE driver
autotunes to get the best performance. There was a message in ucol last
week, and some information can be found in here:
<http://groups.google.com/groups?q=uk.comp.os.linux+hdparm&hl=en&rnum=3&selm=slrn9uueas.95j.mperry%40mperry.lnxpowered.org>

	Any de-bunking of this post? My personal experience is that of
late, hdparm $OPTIONS didn't improve throughput (spelling?) that much
(by the looks of hdparm -tT /dev/hdX).
