When people ask on how to wipe a drive, it almost seems as if the default answer is DBAN and I am not really sure why. Especially when doing commands like
dd if=/dev/zero of=/dev/sda dd if=/dev/urandom of=/dev/sda dcfldd pattern="00" of=/dev/sda dcfldd pattern="FF" of=/dev/sda shred /dev/sda wipe /dev/sda cat /dev/sda | cat > /dev/sda etc
All of these will do the exact same thing and using a tool like hdparm to execute a secure-erase command will be much better than all of the above. Given that it will also erase those blocks on the glist,
So what makes Dban so good and so recommended. Is there a technical reason why it is recommended? To me it seems like a waste of bandwidth and a blank cd.
