8 Formatting only really wipes the superblock, so if you can rebuild it, you've
9 got your data back. Different filesystems use different superblock methods,
10 so formatting with a different fs can make that harder.
12 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
15 we're talking the odd file, or part of file here, nothing more.
17 The data can also been seen, so warping platters isn't enough either.
