Mine too. /dev/ida/c0d2/disc wasn't found. I've decided to live with
just one big partition. Updating the drivers seems to work but didn't
change the behavior. Seemed to means the rpm command reported changing
some things and I rebooted but dmesg reports Compaq smart driver 2.4.5,
but during the rpm run I recall a version considerably higher, like 2.4.26.
Thanks for the try.
Jim.
