How can I delete my SD card so it wont get recovered?

Sometimes formatting isnt enough to remove data, all it does is reset the directory structure and mark all blocks as 'unused'. The data is often still there and is still revorable by someone that knows what theyre doing.

Easiest thing to do is to fill the card up with other data. E.g. just copy movies/music onto it until full. Nobody without the full resources of the CIA behind them is going to be able to recover your photos then.

If you're on a mac, I know their Disk Utility has some features for improving security and completely wiping SD cards.

Applications > Utilities > Disk Utility

Go to Erase and format the drive. Use a 7-wipe or 35-wipe. This fills every sector of memory on the SD card with 0's, where the 7 goes over it 7 times and, yup you guessed it the 35 goes over it 35 times.
