I have an SD card on /dev/sde. The command "findmnt -l" does not show anything mounted on /dev/sde*'. I am the root user. "ls -l /dev/sde*" shows: brw-rw---- 1 root disk 8, 64 Feb 1 13:43 /dev/sde brw-rw---- 1 root disk 8, 65 Feb 1 13:43 /dev/sde1 So apparently the device is writable.
Permissions on device nodes are not related to whether physical device is writable or not. They simply control who is allowed to open device node with intention to write. If permissions do not allow, such open would fail even before attempting to touch device, that's all.
I checked the lock switch on the SD card which is unlocked. After that I want to write an image on the SD card using dd with of=/dev/sde, however I always get: dd: failed to open ‘/dev/sde’: Read-only file system I am using openSUSE 13.1, which is fully updated.
When I mount the SD card, which is mounted as a vfat device, I am also unable to write on the device.
Which strongly suggests that your card for some reasons is read-only.
Any suggestions?
