Re: Advice regarding servers and Wiping Drives after testing

In my organization I have taken a simple Rubber maid tub with a hole
and it is the media destroy bin. Obviously i don't have breaking data
that could be stolen. In your organization you could use a locking
file cabinet with a hole in the top for example.   Once a month i take
all the media out of it and physically destroy the media. I am not the
DoD and don't need to smelter things, but if i just ran a drill thru
the platters a few times I am confident in my work (as well as
corporate policy from top level) that my media is destroyed. sure some
lab geek could rebuild that, but thats not a risk I have.

Steve,

That is not "wiped/overwritten" data.  That is simply deleted, formatted, or
damaged drive.  We are all well aware that is possible, some of us do this
for a living.

      Hi,

      I'd say it is very possible, otherwise organisations would not be
offering
      these services, with "No Fix, No Fee Policies", at confirmed prices.
There
      are a number of testimonials from existing customers:

      http://www.payam.com.au/hard-disk-data-recovery.htm

      If this is possible in Australia, I'm sure that the rest of the world
has
      access to similar organisations ;-)

      Note: I'm not in any way associated with this business, other than
      recommending people contact them directly if they need data recovery
      services.
