My external USB drive is mounted as a read only file system and if I try to safely remove the device using nautilus the system hangs up.
e2fsck reports that the disk has erros but e2fsck can't fix it.
This drive was working fine until the last update and I don't know why this is happening now.
smartctl reports that the device lacks SMART capability so I can't use this for diagnose.
If I plug the drive in other machine that has not been updated yet e2fsck reports that the disk has errors but it can fix it.
The drive works fine and it can be safely removed. But when I plug the disk to the updated machine I have again the same errors.
I've read in the forum that recently others can't safely remove disks but I don't know if this will be related or not.
