I have a NVMe SSD, formatted as NTFS, with mount-point /media/files. When I set it up I had write access to it as expected. After a reboot, only root had the write permission. I cannot use chown on a mounted device, so I checked the /etc/fstab directly. It was set on ‘users’. I changed it to ‘auto,nofail,defaults’.
I have the exact same issue with an USB SSD formatted as ext4, which I would like to use for TimeShift.
What do I have to do to have write permission as a user on both devices?
there are posts about that here
… and in the wiki, very likely …
You need to change permissions on the mount point of the device - the permissions of the device itself aren’t important
those of the mount point are
I would look it up for you, but don’t have time and patience now
you’ll find it …
Ok, now I have write permission on the external SSD, but a warning:
An error occurred while accessing 'Home', the system responded: The requested operation has failed: Error mounting system-managed device /dev/sdb1: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error
The /etc/fstab line is /dev/sdb1 /mnt ext4 auto,nofail,default 0 0
something appears to be seriously wrong here
that device get’s mounted to /mnt
You set that up.
and
the error says that HOME is on that device
which is very likely wrong, confusing for sure
the mount options in fstab look “strange”, too
show your whole /etc/fstab please
and some general system information via inxi
see the posts mentioning “how to provide good information”
Thank you very much for your support. I never labeled it HOME myself, though I created the partition table and formatted it with gparted. But as far as I remember gparted never labled anything HOME by itself.
Yes, I’m sorry, I changed it in between to see if it does not like /mnt as a mount-point, because I think that was the general mount-point for external devices. Therefore, I changed it to a specific folder. I apologise for not clarifying this.
I commented that line out and rebooted. After reboot, the device shows up, but still with only root having write permission. Unmounting, plugging it out and re-plugging it in brings no remedy.
