:smiley:   Hi Nin 13,

Dear member of SanDisk Community, welcome.

Friend, I congratulate you for your message, so detailed and concise.

You have made all the tests with intelligently and expertly.

Do not grieve more, return it because is dead, ist kaputt.

Write protection errors occur when a UFD detects a potential fault within itself. The drive will go into write-protected mode to prevent data loss.
_ There is no method to fix this. _

Do not worry about your personal data, I read in other posts, that is allowed the user to cut or pierce the card, if it was perfectly well identified and with a photo.

_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. Link: http://www.sandisk.com/about-sandisk/contact-us/

To obtain the internal data of the UFD, you can use (portable apps, free): - USB Flash ChipGenius 4.00, http://filecloud.io/rqa7etmv

                                                                                                                                   - USB Flash Deview 2.30,          http://filecloud.io/srp2hegw
                                                                                                                                   - USB Flash DriveLetter 1.30,    http://filecloud.io/vgqzcdyh
