All the back and forth. I say, if you want to be truly safe and if you have the means, give your old hard the same treatment as the Terminator in T2... Other than that, let your security meaures match your threat environment. If you have to worry about National Technical Means, then by all means,

Wiping hard drives

I will be wiping partitions on my hard drive before sending it back to the manufacturer for replacement. I usually prefer dd if=/dev/urandom of=/dev/sdX# for the unencrypted partitions and just over write the first few sectors on the LUKS partition to destroy the header file. I just want to hea
