===Partitions===
All data on device sdX may be **{{color c="red" text="permanently destroyed"}}** by using the command-line interface (warning - this may take a very long time): %%dd if=/dev/zero of=/dev/sdX%%
~-Confirmation of whether or not any non-zero bytes exist: %%dd if=/dev/sdX | hexdump -C | grep [^00]%%

TIP: An easier method, of making data permanently inaccessible, is to perform [[encryption]] of the entire disk/partition and then disposing of the encryption keys.

===Individual files===
Individual files may be made permanently inaccessible by:
~-First, encrypting them
~-then, deleting them in the usual way, e.g.: %%shred -uvz <file>%%
