A dog bit my pendrive and after that I can no longer mount the drive in Linux (Debian-based distro).
I can see the light on the drive blinking and the drive is registered via USB. Is this due to a corrupted file system or is it dead? Is there any way to fix this?
lsusb shows this:

The below image lists the disks and partitions on my machine. Unfortunately, Gparted didn't detect the dog bitten drive.
These are the results of mtab and fstab.

This is the thumb drive that suffered dog bite, if it matters at all.

The pictures show that soft(er) solder has been squished/moved under pressure, causing undesirable cross connections.
The one section would be able to be cleaned up with any half descent soldering gun, and some "solder wick". Solder wick is a fluxed braid of flat copper. In this situation it would be a good method to remove the small ammounts of solder.
Heat the wick on top of the solder you wish to remove, slide wick to new area of the wick (as it fills), and slide across intended removal areas. That method could clean something that small of the solder fairly easily.
Done carefully the solder in the undesired connections would be removed. Then some hope that it was the only problem.
