    Free software to erase the data on your hard-disk is widely available - as Dallas mentioned in the show - but not all of it is safe to use.

    For that reason, and because the BBC is not responsible for the content of external sites, we've decided not to link directly to such products.

    Instead, here's a list of approved software at the Government's Communications-Electronics Security Group (CESG). These products aren't necessarily free, but they are safe.
