This problem happen when after shut down the Windows 8 then I want to open my data partition through Ubuntu 14.04. The error dialog said “Error Mounting…”
I looked for the solution from the forum ubuntu, but I consider that the best option is to edit the mount options of Windows system partitions. I got the solution from this link.
The solution is
1. Open “disks” application
2. Select Windows partition
3. Click small gear icon below it and select Edit Mount Options
4. Set the “automatic mount options” is turned off
5. Add this text “,remove_hiberfile” into mount options field
6. Click Ok
Now you are able to open your data partition without restarting your ubuntu.
Have nice day
