I have a generic pendrive with a problem... I can't copy to inside, delete or move any archive or folder from the pendrive. I don't know how this happens, I do not change any kind of permissions... the only change that I made was change the user password feels days ago.
I try use dosfsck -t -a /dev/sdb1
but without results... some minutes before the Terminal shows:
Contains a free cluster (199578). Assuming EOF. Broke cycle at cluster 119648 in free chain. Unable to create unique name.
I can't even format that... it is useless... anyone can help?
The syslog shows:

and this would indicate a hardware issue such as broken flash memory or a USB bus error.cat /proc/mounts | grep sdb
while it's mounted. And from the logs I see you're removing the drive before unmounting - don't do that!
