completely untrue advice!
the risk is switching off while the "write" light is still working for save (a pretty obvious stupid thing to do) and even then the data can be retrieved with the right software in the vast majority of cases.
the sd card has a switch on the side which prevents writing thus protecting the contents from unintentional deletion. This switch has no relevance when the power is off.
