This question already has an answer here:
After installing ubuntu 16.10 in dualboot with ubuntu 14.04 (which is my prime os) i've suddenly encountered this kind of something:
Error mounting /dev/sdb1 at /media/nerbellion/4d28c2ff-7649-4dd1-b423-3a48b5c695de: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdb1" "/media/nerbellion/4d28c2ff-7649-4dd1-b423-3a48b5c695de"' exited with non-zero exit status 32: mount: Bad message
Error mounting /dev/sdb9 at /media/nerbellion/a7a0a95e-8d8f-4486-8d8b-ae4f09aa11e2: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdb9" "/media/nerbellion/a7a0a95e-8d8f-4486-8d8b-ae4f09aa11e2"' exited with non-zero exit status 32: mount: Bad message
What is the solution to this? It's happened after the installation.
By the way,
/dev/sdb is my secondary external hdd, not the one, containing main os - 14.04.
