Asked by Jan van Emous

after uneventfull upgrade from Ubuntu 12.04lts to 14.04.1lts I can't open my external harddrives.
I get message "U hebt niet de benodigde rechten om de inhoud van ‘janve’ te bekijken." = you haven't got the rights to view the content of 'janve'. simmilar messages appear when trying to open two other disks.
How can I get my rights back for the disks?
I had no problems with Ubuntu 12.04
Disks are of ntfs type

What filesystem do the disks use?

Was 12.04 ok?

File system of the disks is ntfs
Ubuntu 12.04 was working with no problems and all updates were in place before upgrade was started

If Precise worked ok why did you fix it? Precise is LTS and supported til April 2017......

Is that a problem?
I did an upgrade because one was offered. It was not a fix for anything.
That is quite normal when a new upgrade is released. I'm using Ubuntu lts since 08.04 and upgraded at every new lts relaese. Never a problem. Is Ubuntu 14.04.1 LTS a non-stable release?
Is there a fix for my problem. Do I need to go back to Ubuntu 12.04 lts?

No I'm just pointing out that the upgrade wasn't required as the OS was running fine and had lots of support left in it.

I have no other suggestions personally but others may be able to advise. I am not the only helper on this forum.

If you do perform a clean install, I suggest you use Trusty. A clean install will run as expected as there is not all the old fluff from the old install.

Personally I always clean install.

what is the output of
ls -la /media

(or replace /media by the directory where the external hard drives are mounted)

When you want to unplug the drive, do you use the safe removal feature in the OS before unplugging?
What file system is the USB using?

Thanks

I recommend that you safely remove the external hard drives (use the 'eject' button on the left hand side of the nautilus file explorer program), and then re-issue the command

ls -la /media

What is the output?

Thanks for taking the time to try to solve my problem.
I worked around the problem. I connected the harddrives to a laptop with Ubuntu 14.04 installed on it. On the laptop I had no problem to access my files and folders.
After adjusting the rights on the external drives, creating a new account for myself on my desktop computer and reconnected the harddrives to my desktop computer.
Again had access to my files.
I still haven't got a clue what happened during the upgrade to Ubuntu 14.04.

I suggest you look into a backup regime, then you will always know your files are ok.
