  After waiting a while (may be 3 of 4 minutes), i've got an acces to my hard drive.

  I don't know what's happened (it's over my knowledge :) ) but there is
  probably a bug.

  I've already talk about this bug on my LUG :

   - http://gulliver.eu.org/ml-archives/septembre-2012/msg00002.html
   - http://gulliver.eu.org/ml-archives/septembre-2012/threads.html

  May be there is a problem with the uas driver ?

  If there is a bug, i can help you to solve it ! :)

  See you,

  Arnaud
