Having worked quite a bit with Debian on decently sized IDE machines, I
can't say I've ever heard of Debian doing anything with hdparm in the
init scripts. 'grep hdparm /etc/init.d/*' returns nothing.
In addition the Debian woody system I had running DMA100 with 7200rpm
drives with Reiserfs burnt from day one (well, there was a cap because
of the pretty ancient other hardware, but it was old enough hardware I
was testing that it made sense that there'd be a hit on disk
performance)
Ed - are you sure the kernel hasn't detected a bad drive/controller
combination and has *intentionally* disable UDMA to prevent data
corruption? Are you using the Good/Bad Drive Firmware protection?
Something seems odd to me...
