Phillip Pearson - web + electronics notes

tech notes and web hackery from a new zealander who was vaguely useful on the web back in 2002 (see: python community server, the blogging ecosystem, the new zealand coffee review, the internet topic exchange).


Linux UDMA

hdparm -d1 /dev/hda turns on UDMA for /dev/hda. (It wasn't on by default for me).

To test to see if it's working, use hdparm -Tt /dev/hda. If you only get 3 megs/sec when reading, either UDMA is off or you are using a really old drive ;-)
