I think you're remembering a problem we had with the mac68k port where 
the Mkfs application under MacOS wasn't clearing out enough of the 
first part of the partition.  This shouldn't be a problem for the 
macppc port unless the user prepared the disk using an old copy of the 
Mkfs utility. I don't think that's the case here since the user is 
using an IDE disk which isn't supported by the MacOS utilities used by 
the mac68k port.
