 Posted: Wed Jun 20, 2012 7:44 pm Post subject: Securely erasing flash media |
 |
|
Now I understand flash media is a different ballgame to conventional secure deletion on magnetic drives. However, I was under the impression that encryption was the answer.
To test this, I fully AES encrypted an 8gb flash drive with a 40 char password. I then formatted the drive to fat32 and loaded up FTK.
I was able to recover about 20 images from the drive, granted half of them were scrambled.
What gives? |

| The images were not in the encrypted container or the container was decrypted. |

Yeah that would seem the case, I'm just at a loss of explaining why?
Error when encrypting maybe? truecrypt should have done the whole drive.
I tried a second time and nothing was recoverable, only this time I made sure to zero the drive once. I can't see how that would make a difference though. |

Check out this paper : Reliably Erasing Data From Flash-Based Solid State Drives (google and it'll appear at the top of the list).
It explains very good what the issues are with SSD's and wiping. |
