I think this problem happens when a CD or other 'removable' disk is mounted while the installer is run. I don't remember anyone saying that he fixed the problem and the exact solution. Somewhere in the System Folder or elsewhere is a file that needs to be deleted but I don't know which one in particular.

zbell gives a few suggestions in this post; hopefully all of those steps aren't necessary.

If anyone figured out which particular file to remove do share.
