My USB stick got corrupted. I am not even able to format it as it is not found properly by my OS (Ubuntu 16.04).

What I tried:

It is found by neither fdisk -l, lsblk nor gparted.

It is shown by lsusb:

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

Logs from dmesg after plugging the stick in:

>dmesg | tail -n 11

usb_storage module seems to be loaded properly:

>lsmod | grep usb_storage
usb_storage            69632  1 uas

gnome-disk-utility finds the USB stick but provides only few information and does not enable formatting it :

Any help appreciated, thanks!

EDIT: on udevadm monitor I get following lines after plugging it in:

You can try according to this link: Can't format my usb drive ... Analysis of the problem

Particularly you can try the tips in the list

  • 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

In your case, if you still cannot see, write to, or format/restore the USB stick as a mass storage device, as a drive, it might be damaged beyond repair.
