[ale] destroy old drives

[Jim Kinney]

I like to write clear text red herring files onto a LUKS encrypted
drive to be disposed of. So delete the LUKS header, overwrite it with
/dev/random. Reformat the drive as fat32 then add:
Files named "bank_codes" and then filled with random generated account
numbers and passwords.Files named "my passwords" and filled with random
usernames, accounts, and passwords"Files named "my new access list"
filled with real usernames gleaned from facebook, google, etc. but
random passwords
This works real well on a fresh install win10 with no password on the
default user account. Keeps the schmucks busy testing :-)

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
