I originally had this message along with a read error, so appeared in
pairs. This never caused any real problems on my PC but disappeared when
I updated my Bios.

I would start by checking the cable & power connector to your drive -
unplug, reinsert or swap in another if possible. You may need to test
your disc using diagnostic s/w from its manufacturer's web site.

Take a look at these two sites.

Then goto your motherboard manufacturer's website and get the latest bios
and see if it resolves this problem. If it doesn't, contact your
motherboard manufacturer and ask them to resolve this issue, citing the two
links above.

Most current motherboards, if they haven't had the issue resolved already,
have fixes forthcoming in a future bios upgrade.
