Hi list.
Recently I've had trouble with my software raid which have been (mosstly)
resolved with the help of people from the linux-raid list.
While doing that, I stumbled over these lines in my /var/log/messages:

Now, is this a broken IDE controller or harddisk? Because smartctl claims
that everything is fine.

I run short tests every night and long tests every sunday to check the
devices. They're brand new, although I know that that isn't always a guarantee
that they also work.
If it's important, I've attached the IDE specific output of the boot messages.

hde has since been removed from the machine, but the pdc20268 is still
present.
If someone has an idea if it's the controller or the disk or anything else
I'd very much appreciate any help you can offer!
Greetings,
Benjamin

Today, memory either forgets things when you don't want it to,
or remembers things long after they're better forgotten.
