[SOLVED] USB external drive - permissions

RichAustin · 2014-08-03 12:02:16

Hi All

I just installed Arch again for the first time in about 4 years - the installation has changed quite a lot but for the better I think. I've got most things sorted out but I can't get my external Toshiba drive to work correctly. I can't create folders, move files etc. I thought I'd try adding the drive to the storage group and give permissions to that group:

sudo chgrp storage /run/media/richard/toshiba
sudo chmod 775 /run/media/richard/toshiba/

Nautilus tells me, via Properties on the drives root node:

Owner: Me
Access: Create and delete files
Group: Storage
Access: Create and delete files
Others: Access Files

This is exactly what I expected but I still can't delete or create folders etc. I thought I may be able to set the permissions of the individual folders like this:

sudo chmod 775 -R /run/media/richard/toshiba/

This doesn't work either. I installed ntfs-3g just in case and had a look around on the Net but am not seeing anything that seems more likely to work than the steps I've already taken. Any ideas please?

Thanks
Richard

BTW: It's great having a real Arch running again, I just haven't had time to set it up for the last few years, I've been using ArchBang etc. instead which isn't the same at all.

I ended up changing the ownership of /run/media/'user' to the user, chmod'ed to 750 and haven't had a problem yet.

What do you mean "just in case"? Does the drive have an ntfs filesystem, or something else?

If it is ntfs, did you remount it after installing ntfs-3g?

Can you post the output of `mount`?

Hi Trilby

What I meant by "just in case" was that one of the posts I read mentioned ntfs-3g and, since I do have a Windows 8 partition as well, it wasn't going to hurt to install it. The drive auto-mounts when I start Gnome.

The output of 'mount' is:

EDIT: The Toshiba drive is the last one in the list:

/dev/sdb1 on /run/media/richard/toshiba type ntfs (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0177,dmask=077,nls=utf8,errors=continue,mft_zone_multiplier=1,uhelper=udisks2)

Well that's not just a "just in case" as that is an ntfs filesystem. So the behavior you observe is expected without ntfs-3g.

Now you've installed it, but changes won't take effect at least until it's remounted*, this is why I asked if you had remounted it. Have you?

*note: remounting is definitely required after installing ntfs-3g as it provides a new mounting program. It *may* also require loading kernel modules, in which case if the installed kernel is different from the running kernel (uname -a != pacman -Qi linux) then it would also require a reboot or kexec.

Hi trilby

I've now rebooted the system, I realise now I should have done that after installing ntfs-3g (thanks for pointing out what should have been blindingly obvious!) and it now works fine.

Thanks for your help, and sorry for being so dumb.

I hadn't thought of that, thanks for the idea.
