Has your computer died?  Did you get an upgrade?  Did your Hard Drive die and you need to throw it out?  I don't want to scare people, but there is TONS of personal information on that computer or Hard Drive that bad people can use to steal your identity.  A format is not good enough to protect you, as the data is still on the drive until something writes over it.  Even then, the really good bad guys (oxymoron?) can even read it if it has been written over once, sometimes twice...

What I willl do is give you double protection from these data thieves.  I will first write over all your data three to seven times with random data, ensuring no hacker could ever read the data on it if it got into their hands... The second level of protection I use is old fashioned distruction.  I take apart the hard drive to all the mechanical components, spray them all down with water and alcohol, and turn the data disks themselves into a nice wind chime I hang in my home... No way anyone can get this data, even if they broke in, good luck getting anything off these disks...

What is the cost of this security?

3 random wipes and drive destruction - 1 Drive - $25
                                                                - 2 - 5 Drives - $20 Each
                                                                - 5 or more - $10 Each

Add $5 for each addition random wipe you would like me to perform.  The US Department of Defence uses 7 wipes, the most I feel anyone would ever need.
