Additional harddrive only in read mode

I have additional HDD:

cat /etc/fstab
# /etc/fstab: static file system information.
...
# External 1TB drive for some data
/dev/disk/by-uuid/20A949F121CEADD8 /mnt/20A949F121CEADD8 auto rw,acl 0 0

but its always mounted in read only mode..

Partition type of this HDD is NTFS.

uname -a
Linux My-Tower 5.14.0-1052-oem #59-Ubuntu SMP Fri Sep 9 09:37:59 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

I tried from other SO but:

sudo mount -o rw,users,umask=000,exec /dev/sdc1 /mnt/hdd_data
The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Falling back to read-only mount because the NTFS partition is in an
unsafe state. Please resume and shutdown Windows fully (no hibernation
or fast restarting.)
Could not mount read-write, trying read-only

what can I do to change it for normal usage?

thanks

You've not provided any OS/release details, but have you checked system logs for issues that will cause a RW mount to *flip* to RO? You also didn't provide us with any clues as to what sort of *file-system* you're trying to mount.

You've added kernel details but still not OS/release details (it's an OEM kernel which would require more specific details about your hardware for us to interpret the results into your *unstated* Ubuntu product/release details, so why not tell us?) Have you explored system logs for clues? (*Its the first place I'd look, and I still don't know what OS/product/release details though I now know you're using an OEM kernel on that unstated release*)

Does this answer your question? [How to make read-only file system writable?](https://askubuntu.com/questions/47538/how-to-make-read-only-file-system-writable)

You've still not provided any OS/release details; but you've highlighted it's NTFS and also it's in an *unclean* state, thus any attempt to mount it RW is automatically *flipped* to RO to prevent dataloss. Close the file-system making it clean (on the machine that has left it *unclean*), then you can mount it RW (ie. turn off hibernation etc. which include fastboot on windows which is just a form of hibernation; fastboot resumes from a hibernate file created during upgrades).

ok thanks guys for help!

I found here how to mount it properly: How do I use 'chmod' on an NTFS (or FAT32) partition? then I realized about NTFS issues so I did fix:

sudo ntfsfix /dev/sdc1

and its ok now :)

That can be a dangerous fix; it'll allow you to mount it RW on a GNU/Linux system like Ubuntu, but can create problems if that drive is later used on a windows system that believes that system is currently *hibernated*, ie. it may ignore any changes working from the image it stored of what the file-system was like before the machine entered the hibernate/off mode. *Ensure your backups of data on that drive are up-to-date first! and don't forget the corruption may take time before its noticed if the cause was hibernate/fastboot*

@guiverc thanks but that Issue was due to that in the past there was some Windows there, not I keep on this HDD only data. So no problem at all :)

I had the same issue. .In my case, I just needed to shutdown windows properly.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
