Re: [foxboro] Seagate ST38410A hard drive -- Summary

I have also seen the bad magic number message from format.
It was from using a non-Sun supplied disk and therefore not partitioned 
using the Sun scheme.

Just start format and ignore the message, select the disk and use the 
label option.
Exit from format and restart. You should then get back in without the 
error message and see that the Sun style partition table has been installed.

You need to use Frits' method to use the disk then though as it will not 
have a geometry that the Foxboro scripts will understand.
