You can erase SD card using a command line tool called shred (manpage)

You can also refer to this discussion in askubuntu. How to delete file(s) in secure manner?

OR

For deleting everything on phone, Hard reset is OK. But I recommend flashing the original phone firmware. You can get instructions at XDA
