Emergency wipe SSD I have a SSD drive with LUKS encrypted partition. How to discard all data with one command? Or damage it to non-recoverable state? Even if partition is in use.

If your SSD is encrypted with LUKS, erase the header is good enough

e.g


dd if=/dev/urandom of=/dev/sda1 bs=512 count=20480
