Raspberry Pi USB Stick Destroyer

Use a Raspberry Pi to wipe a USB thumbdrive

This is a quick hack to securely wipe a USB thumbdrive with a Raspberry Pi.

An LED attached to pins 11/12 will flash while the following is done:

• All of the data on the stick is shredded. 8GB takes 20-30 minutes
• New partition table loaded from the SD card, creates new 100MB partition at /dev/sda1
• Pin 11 held high if when complete

If any of the commands fail pin LED will remain off.

All commands, output and errors logged to /var/log/stick-destroyer.log
