I'm having a problem with a USB stick I use for university (it includes important files for me). Unfortunately my laptop does not recognize it.

I have tried lsblk but it doesn't even show up, neither in disks utility nor in gparted.

The only thing I imagine might be handy are the last lines from dmesg.

dmesg log

Note that:

  • I have no other USB drives connected
  • This USB stick does not work on university's computers

  • You can try according to the following link and links from it. But don't try to format or restore it, if there are valuable files. Can't format my usb drive. I have already tried with mkdosfs and gparted – sudodus Mar 13 '18 at 20:33
  • Well, after applying all the commands from paragraph 3 (when drive cannot be found) i had no luck! Can't seem to detect it, so the last resort would be mkusb, which from what I understood you wouldn't advice if I don't want to loose my files. – Korina Moss Mar 13 '18 at 20:54
  • That is right, but on the other hand, if the system does not detect the drive and lsblk does not show it, mkusb will not reach it (it depends on lsblk). The alternative to clone the drive with ddrescue will probably fail too in your case. See this link for more details. Scroll down to 'Advanced repair of a partition table, file system and/or recovery of files'. I am sorry, but I think that your drive, the USB stick, is damaged beyond repair. – sudodus Mar 14 '18 at 09:40
