I understand that writing zeros over the file should permenately delete the data but couldn't the data be cached elsewhere on the drive, especially with journalling filesystems?? |

I have heard the same thing. I have watched some of them on TV get data |
| 31 |
off some unbelievable drives. Some had bent platters, serious |
| 32 |
scratches, been formatted a few times etc etc etc, After all that, |
| 33 |
they still got enough of what they wanted. They put a chemical on one |
| 34 |
and you could see the data with your eyes. It looked like a round bar |
| 35 |
code sort of. |
| 36 |

| 37 |
Whatever you use, if it does it quickly, it ain't worth the time. |
| 38 |
Really erasing something and rewriting data over it takes a bit of |
| 39 |
time. That little light should be on a while. I still wouldn't count |
| 40 |
on it. Shreading it and putting it in concrete may be a good idea. |
| 41 |
Maybe putting it in a MRI machine would help too. I would leave the |
| 42 |
room though. O_O |
