I'm currently with the ub driver, so I tried |
| 13 |
|
| 14 |
sanduleak ~ # hexdump -C /dev/uba |
| 15 |
hexdump: /dev/uba: No medium found |
| 16 |
hexdump: /dev/uba: Bad file descriptor |
| 17 |
|
| 18 |
I'll try again with the usb-storage driver after a reboot, but I fear |
| 19 |
I'll have the same problem. |

There is indeed an encryption feature on this key. I've never used it (I |
| 27 |
haven't even downloaded the windows-only software allowing to use it). |
| 28 |
Can it be related to this problem ? |

I'm not even able to dd the disk... (No medium found) |

thanks for all that information. |
| 46 |
|
| 47 |
So my next steps are : |
| 48 |
1. Switching back to usb-storage |
| 49 |
2. Trying to dd the disk |
| 50 |
3. That doesn't work, trying to get access to another computer and see |
| 51 |
if I can do something. |
| 52 |
|
| 53 |
By the way, I can afford losing the data on the key. I mainly want to be |
| 54 |
able to use it. Does that giev you other ideas ? |
