Dear member of SanDisk Community, welcome.
Please friend, do not grieve more, return it, is dead, ist kaputt…
You might have a pleasant surprise, if can contact with SanDisk Technical Support who will replace the device if it’s authentic and is within warranty.

To obtain the internal data of the UFD, you can use the portable utility (free): USB Flash ChipGenius 4.00, http://filecloud.io/_cpweb34i
