My computer has a 525GB SSD and a 2TB Western Digital HDD. I have a 147GB partition running Windows 10 and a 367GB partition running Ubuntu 16.10. The SSD is running completely fine, but the 2TB drive sometimes mounts as Read Only. This seems to only happen when I have previously booted into Windows. Restarting into Ubuntu, no matter how many times I do it, does not fix the issue. If I reboot into Windows, however, and then back into Ubuntu, the issue resolves itself. This is not an ideal fix, and I would like a way to have the drive mount properly. I should also note that I have to click on the drive from the Unity task bar in order to mount it, as it does not automatically do so on login.

I've read a few things online (though they were just for general troubleshooting of a drive mounting as read only) and the general consensus is to either run chown or to try remounting. However neither of these solutions have worked for me. I've tried a few other miscellaneous things to try and fix the drive but nothing has worked.

EDIT: The WD HDD is formatted to NTFS. It has no partitions on it either.

  • The WD drive is formatted how? Can you show lsblk? Also, what messages do you get when you try to remount the WD drive read-write? – AlexP Jan 02 '17 at 20:35
  • Make sure your unmounting the device properly and completely after each use especially on windows. – George Udosen Jan 02 '17 at 20:40
  • @AlexP Whoops, apologies. I'll edit my original post after I make this comment. The WD drive is formatted to NTFS. – Eamonn Jan 02 '17 at 21:22
  • @George The drive is internal so I shouldn't have to unmount it when I switch the machine off, should I? – Eamonn Jan 02 '17 at 21:23

It seems to me that it is an issue with Windows, that Windows is sometimes leaving the drive in a state, that is not good. I suspect that Windows is hibernating or using fast startup which is a kind of semi-hibernating, when you shut it down. But when you reboot Windows, it is not doing any of that, and the file systems are clean.

I suggest that you check if this is the problem, and if it is, do not use hibernation, and/or turn off fast startup in Windows. You can find several links to tutorials how to turn it off, for example this one:

  • I will follow your suggestion on disabling hibernation and fast startup. Is there any kind of way I can check (from Linux) if this is actually the case? I mean I'm sure there's no harm in disabling it but I'd like to check to see if the drive is being left in any kind of state. Thanks for the reply, and I'll test this as soon as I possibly can. – Eamonn Jan 02 '17 at 21:27
  • Maybe this behaviour, that Ubuntu is suffering from ;-) I suggest that you check in Windows according to the link in my previous comment – sudodus Jan 02 '17 at 21:30

My problem was solved very simple. I have Ubuntu and Windows on my pc. One day in Ubuntu a partition appeared as "read only" and none of the above solutions worked. I solved it by restarting, entering windows and going back to ubuntu. It worked more than once.
