Problem mounting USB HDD with right access permissions!

Baltazard2013 · 2015-01-01 13:42:53

Hi Everyone, Happy new year and thank you for reading.

Well, I've installed Arch and setup pretty much all I want, except I'm having a problem with file/folder permission on my external hard drive.
I don't have this problem with other *ubuntu and its derivate distros; I've experienced this problem only while using Arch.
So I've decided to start fresh with only Arch as my OS on my laptop, because I feel that Arch suit my need.
Anyway, when I plug my external HDD via usb port, I can read and write but for some reasons I can't modify the existing data (say delete or rename).
I've tried to change permission on the files/folder but it stays the same after reboot/re-insert.
While I don't want to mount the USB-HDD on boot, I do want to have the USB-HDD mounted when I plug it in and have full access to my existing data.
I scoured the forum and there seems to be few posts related to my problem, but not a simple fix is provided.
I hope someone will provide me an answer.

Many Thanks

Please use bbcode when posting shell output. I'm not an ntfs expert, but what about changing the ownership on that mount point to your user/group?

Baltazard2013 · 2015-01-01 14:02:35

Done, thanks, i didn't know that (bbcode)
no idea how to change ownership, and I don't want to add the USB HDD to fstab.

I dunno... I don't an NTFS external (just ext4) and there the permissions are changed on the mounted device and the mount point inherits them on the mount. Not sure how to accomplish it on ntfs without a umask/fmask. Perhaps someone else knows or the answer is out there just waiting to be found.

NTFS has no permissions, in particular, but the mount point has. Better you see this wiki and this chapter
If you don't have installed udisk2, then you should.

It seems that there isn't an easy fix, I feel that the solution is in fstab, but I don't really want to mess with it.
Udisks is kind of a risky business, I'm not sure but I will give both option a try.
Thx

karol · 2015-01-02 01:15:24

What would you define as an easy fix then? What exactly are the risks you're talking about?

Ubuntu has done that risky business, instead of you. Arch gives you the power to administer your thing.
Knowing what to do with udisks gives you the power to configure what you need. But it is no harm as long as you don't write anything on the NTFS partition. If you want to write then it's implied that you're doing a risky business

Install ntfs-3g package if you haven't already then see the Archwiki ntfs-3g entry, the part about editing /etc/fstab in particular.

OP seems uninterested in actually reading the wiki or understanding their "problem"...

Baltazard2013 · 2015-01-02 20:08:45

Many thanks guys, but, I did install "ntfs-3g" long before posting my problem; and if you read well I did mention that I do not want to change fstab just for the sake of an external HDD I plug once in a while (which make sense), also if I extrapolte to another level, that means I will add every USB pen I insert to the fstab!
So, maybe fstab is one solution but not the right solution.
I will keep searching, as I'm not convinced this is right.
Thx

Not sure if it's useful or not but...

You aren't convinced it is right. You think udisks is a risky business. What exactly is the issue?

Install ntfs-3g and add custom mount options (as per the wiki article) for that filesystem in your udiskie config file. That's all there is to it.
