are you totaly sure it was totally zero'd?
The best thing to do is take the disk
and place it as a secnd drive on your
machine.. failing that, th 2.1 boot disk + fixit disk can help but
could be laborious..

a C program to scan for the magic number in the 2nd block of the 
unix section should not be to hard..

then zap it with disklabel -iu
