software or hardware raid? It can make a difference. I'm not an expert 
on this but it is worth looking that sort of thing up on google. Also, 
you may have trouble finding Ubuntu-specific answers because your 
hardware is quite different from the norm.

Another possible problem could be a bad cd. You should md5sum or sha1sum 
it and check to see it matches that on the download server.
