fstab mounting: permission setting

Question

I have an issue with mounting my NTFS data partition (separate drive). This is the drive (fdisk -l):

Disk /dev/sdb: 232,9 GiB, 250059350016 bytes, 488397168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00095dd3

Device     Boot Start       End   Sectors   Size Id Type
/dev/sdb1        2048 488396799 488394752 232,9G  7 HPFS/NTFS/exFAT

I mount it through a fstab entry with my user and my user group and full permissions:

/dev/sdb1    /home/asche/dtn     ntfs-3g  defaults,nls=utf8,umask=000,auto,uid=1000,gid=1000           0  0

It shows up normally in Nautilus and in terminal (ls -ll ~):

drwxrwxrwx  1 asche asche    4096 Okt 22 21:42  dtn

Also all the data is there under ~/dtn. I just don't have permission to delete, cut, rename etc (so, I guess read-only is granted).

Any ideas on how to change my fstab file? I have tried quite a bunch by now...

I am running Ubuntu 18.04 LTS and Win10 in dual boot.

Please edit your question to say which version of Ubuntu you are using. — graham, Oct 26 '19 at 13:45
Thanks. You may find this link helpful https://askubuntu.com/questions/1092195/fstab-edit-for-nas-mount?rq=1 and this one https://askubuntu.com/questions/1032237/why-is-mount-cifs-not-working-in-fstab-any-more-after-upgrading-from-16-04-to-18. I think you need to add vers=1.0 to fstab — graham, Oct 26 '19 at 14:18
Tried it - no change in behaviour though /dev/sdb1 /home/asche/dtn ntfs-3g vers=1.0,defaults,nls=utf8,umask=000,auto,uid=1000,gid=1000 0 0 — Klaster, Oct 26 '19 at 14:36
Okay, your links got me on the right track! It was due to Win10 not shutting down decently in dual boot... Need to shutdown windows with pressing SHIFT + Shut down Thanks! — Klaster, Oct 26 '19 at 14:51
Excellent news. Post that as an answer to your question and then wait a few days to mark it as accepted. — graham, Oct 26 '19 at 14:53

It's not a Win 10 partition, but a partition used by both OS. But yes, the issue is the same. (also: https://askubuntu.com/questions/145902/unable-to-mount-windows-ntfs-filesystem-due-to-hibernation) — Klaster, Nov 12 '19 at 08:18

The solution lay not in any Ubuntu settings, but in the dual boot with Windows 10. Windows 10 has a fast boot option that hibernates the system instead of shutting it down decently. This results in ubuntu being able to mount the NTFS disk in read-only.

To shut down Windows 10 effectively, press SHIFT + Shut down button or follow instructions in the internet (e.g. this tutorial)
