pdisk help

[Chris Saunders]

Hi Eric,

I've been trying to run as root with no success - I 'su' to root the run
the program and I still get 'map is unwriteable'.  Perhaps my problem is
with which dev I'm trying to use?  I'm going for /dev/disk0 or
/dev/rdisk0.. should this be like /dev/hdb or something?

Thanks
