I've had the same problem on different machines. There are different solutions 1. It could mean that your hard drive is going bad. FreeBSD seems more sensitive to this than some other O/S's to it. 2. It can sometimes be fixed by changing to a better quality IDE cable 3. It can sometimes be fixed by changing (I only know how to do this with a particular drive's vendor's downloadable utility) UDMA from 66 to 33 4. You can simply tell the machine not to try UDMA mode with sysctl.conf (though I'm not quite sure how to do this--I did a search on deja and the results were conflicting with each other. Lastly, it can, it seems often be ignored without any real problems.
