How can I scrub both my internal and external HP9000 disk drives

Well... start with some dish soap in a bucket, add hot water. Then with a scrub brush...

just kidding!

Can you be more specific about what you are looking to do?

Thanks

It depends upon how thorough
you want things to be, and
upon whether or not the disks
are currently in use (mounted).

Although we have a product to
do this, I always try to provide a free suggestion, too...

You can effectively overwrite
your user data by looping
and copying a large file
(e.g., /stand/vmunix) to
the disk in question...
after first deleting (rm)
all the user files.
If you do this until the
disk fills up (note: you
want to be root, so you
can get the entire free space
allocated), then you've
effectively "scrubbed"
your user data.

Another possibility is to
boot to the offline diagnostics and look at
DTDUTIL (inside ODE),
or at some of the disk
diagnostics (which require
a password...sigh).
A crude way to do it
with DTDUTIL is to copy
a blank disk to tape, and
then use that tape to
copy blank data to a
now-unwanted user disk.
I can't recall if DTDUTIL
requires a password to run.

Or, email info@allegro.com for info
about our WipeDisk/UX
product. WipeDisk can
erase a single disk, or
you can say "all". It defaults to a single pass
of writing zeroes (nulls)
to the disk, but you
can optionally ask for a
5-times overwrite, which
is what some security
groups like to see.

Oops...sorry about
the ...didn't
see the "please don't advertise"
until *AFTER* submit was
hit ... because it displayed
on the "thanks for posting"
page (which, BTW, took 10
minutes to come up :)
