A quick Google of that indicates that the problem is with hald, and
there are documented fixes, at least to keep hald quiet so it doesn't
keep reporting the problem.  Of course, the problem actually starts with
the drive.

the ATAPI driver -- different kernel.

Of course, that fix would mean that incompatible media would be
misreported as not present...
