Why is writing on auto mounted partition not possible?

Question

Despite it has rw option. An extraction of fstab:

/dev/disk/by-uuid/0109cc2c-414c-42dc-8a99-3ffe529020fe /mnt/0109cc2c-414c-42dc-8a99-3ffe529020fe auto rw,exec,noatime,x-gvfs-show 0 0

This entry was created by the standard drives tool of lxde on debian.

what makes you think it is unwriteable? do you have read permission to the entire path of the mount point, and write permission to the target directories you wish to write to? — Frank Thomas, Commented Sep 19, 2018 at 19:33
I have no write permission. It's a new drive and I can't copy or save any files on it. — Asklep, Commented Sep 19, 2018 at 19:40
did you format it? your disk ID is pointing to a partition, right? Just for terminologies sake, permissions refers to files system permissions where as the rw option on the mount is its Mode. — Frank Thomas, Commented Sep 19, 2018 at 19:59
thanks @Frank now I understand (didn't know that). See my answer which I just remembered from another situation with USB drive. — Asklep, Commented Sep 19, 2018 at 20:09

I had to change the owner by:

sudo chown -R userme:userme /mnt/fb7bd4xxxxxxxxxx

It might have happend since the partion was used before from a nother debian linux which I tried but deleted (by installing a new one).

gotcha. yeah this is a common problem when a disk from an older build was has contents that were owned by a non-root account (root is usually fine because the UID and GID for root are always the same).
