I would do the following, and call it good: dd if=/dev/urandom of=/dev/sdX bs=1M count=100 This will wipe pseudorandom data to the first 100MB of the drive, which should wipe out any of the encrypted header information at the beginning of the partition. Further, notice that I'm using /dev/sdX rather than /dev/sdX#. Sending it to the drive should wipe the bootloader also, as well as take out the partition information. -- . o . o . o . . o o . . . o . . . o . o o o . o . o o . . o o o o . o . . o o o o . o o o
