for People having the same Problem: I made a complete Image of the Stick (in my Case Micro SD Card) Restore the Image to new MicroSD Card Run fsck.ext4 -f /dev/sdb8 (/dev/sdb8 replace with you damaged Partition) repair the FS in this Step (Say yes to repair the Errors) After it is done, put it in your Raspi ot whatever it was, and the it works for me perfect.

• Make a complete image of the stick (in my case, a Micro SD card).

• Restore the image to a new MicroSD Card.

• Run

  fsck.ext4 -f /dev/sdXY
  

  (where sdXY is replaced with the actual device name of the new MicroSD card)

  Anser "yes" if asked whether errors should be repaired.

• After it is done, it worked fine for me again.
