since today I get the following message when inserting usbstick/sd card:

Aankoppelen bestandssysteem is mislukt
Error mounting /dev/sdb1 at /media/wouter/Kali Live: Command-line `mount -t "iso9660" -o "uhelper=udisks2,nodev,nosuid,uid=1001,gid=1001,iocharset=utf8,mode=0400,dmode=0500" "/dev/sdb1" "/media/wouter/Kali Live"' exited with non-zero exit status 32: mount: block device /dev/sdb1 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so

(udisks-error-quark, 0)

Here is the output of dmesg | tail

It was working perfect until now. I do have ntfs-3g installed, so this could not be the problem.

  • Please be more specific - what kind of media to you try to mount? How is it connected? What do expect on the media?

  • The last time this external drive was connected to a Microsoft Windows system, did it work? Did you disconnect it politely, or just yank the cable? You should probably mount it on Windows the dismount it properly.

Indeed, it was a matter of corrupt stick. I had a few memory sticks/sd cards after each other which gave me the same error which made me think that it was a settings fault, but it turned out to be the sticks themselves. Problem solved
