USB stick não reconhecido pelo fdisk

Question

Meu pendrive foi corrompido. Eu não sou nem capaz de formatá-lo, pois não é encontrado corretamente pelo meu sistema operacional (Ubuntu 16.04).

O que eu tentei:

Não é encontrado nem por fdisk -l , lsblk nem gparted .

É mostrado por lsusb :

> lsusb | grep Kingston
Bus 004 Device 016: ID 0951:16a2 Kingston Technology

Registra de dmesg após conectar o stick em:

>dmesg | tail -n 11

O módulo usb_storage parece estar carregado corretamente:

>lsmod | grep usb_storage
usb_storage            69632  1 uas

O gnome-disk-utility encontra o pendrive, mas fornece poucas informações e não permite formatá-lo:

Qualquer ajuda apreciada, obrigado!

Você pode tentar de acordo com este link: Não é possível formatar meu drive USB ... Análise do problema

Particularmente, você pode tentar as dicas na lista

• On some pendrives and on many memory cards there is a small mechanical switch for write protection, that can toggle between read/write and read-only. You might have set it read-only without intention.
• Reboot the computer and try again to restore or wipe the first megabyte with mkusb.
• Disconnect other USB devices. Sometimes USB devices can disturb the function for each other.
• Try other USB ports and another computer.
• Try another operating system (Windows, MacOS) in another computer.
• If you still cannot wipe the first megabyte of the drive, and the drive is read-only, it is probably 'gridlocked', and the next stage is that it will be completely 'bricked'. There is a limit, when you have to accept that the pendrive is damaged beyond repair, at least with tools available to normal users like you and me. See this link: Pendrive lifetime

No seu caso, se você ainda não puder ver, gravar ou formatar / restaurar o pendrive como um dispositivo de armazenamento em massa, como uma unidade, ele pode ser danificado além do reparo.
