Formatting only really wipes the superblock, so if you can rebuild it, you've |

got your data back. Different filesystems use different superblock methods, |

so formatting with a different fs can make that harder. |

Until you flip every single bit on the disk, at least twice, some 3 or more |
13 |
times (naturally a single flip isn't enough, you'll have a mirror image!), |
14 |
something can be recovered, if you've got the money, skill, and patience. But |

we're talking the odd file, or part of file here, nothing more. |

The data can also been seen, so warping platters isn't enough either. |
