Ok. FWIW I decided to write zeros to the drive until I can take the
drives out and DBAN them.
But format - analyze - purge sounds like a good solution in the future
if the machine is not going home with me.

Seems to me that it wouldn't be too big an issue to port it to boot
from something like Debian Sparc and sense most of the common

Don't know yet. I may put OpenBSd on it then stick it on the web
directly as a webserver/file server for a domain I've been sitting on

diligently. It is my mission to teach the precious value of peace to
the children who will one day own the world. I will say it again: My
