How do I erase a K class disk (a3353a)

[Stan Sieler]

It depends upon how
thoroughly you want to erase it.

If you just want to overlay the data with something else,
you could copy multiple copies
of, say, /stand/vmunix to it.

Of course, the ease/difficulty of erasing it
may depend upon whether or
not it's part of 1 or more
logical volumes.

It's fairly simple to write
a trivial program that does:

open /dev/rdsk/

and then loops, writing
a zeroed-out buffer to
it over and over until
write() returns an error.
(Run as root, of course)

Our company happens to have
an "erase disk" product,
but I don't know the etiquette
of posting info like that here. (At least I discussed
two free ways of doing it :)
