I'm having a strange issue with a duel boot I set up on my laptop. I have one hard drive (a rather small 120gb ssd) split into thirds. on the first third I have windows 10 installed. On the second I have Ubuntu 15.04. And the third is my storage partition. The problem here is after a few days I an unable to mount the storage partition in Ubuntu (still able to mount on win 10 just fine) and it throws the following error: 

error mounting /dev/sda4 at /media/joe/B628F68528F64441: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000" "/dev/sda4" "/media/joe/B628F68528F64441"' exited with non-zero exit status 14: The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Failed to mount '/dev/sda4': Operation not permitted
The NTFS partition is in an unsafe state. Please resume and shutdown
Windows fully (no hibernation or fast restarting), or mount the volume
read-only with the 'ro' mount option.

I have tried unmounting the partition on windows, no dice. I have tried formatting the partition on windows, no dice. I have tried formatting the partition on ubuntu, dice. However after a few days the drive again is inaccessible.

Any ideas what is causing this?

Thanks in advance,

Joe

You might start Ubuntu without properly shutdown the windows. If you are restarting and switch to windows to Ubuntu cause problem . similarly hibernate also like that so better if you try to switch to Ubuntu, then let the PC shutdown and give a little time then start with Ubuntu. Because file system of Windows is NTFS in Ubuntu its different so your operating system may confuse this student transformations.

It seems that you have not turned off fast startup option in windows. Fast Startup (a.k.a Hybrid Boot or Hybrid Shutdown) is turned on by default in Windows.
To turn it off : Go to Control Panel > Power options > Choose what the power buttons do
And the uncheck the Turn on fast startup option.

Hope that helps.

  • Hey! This worked! for now at least. I'll see if it continues to work after a few days of use on both. – JoesLost Sep 07 '15 at 16:50
  • Also note that whenever you'll hibernate windows and then open ubuntu, this error will show up. For more help see this –  Sep 08 '15 at 01:24

dual boot ubuntu 14.04 and WIN10 share NTFS problem same as described above:

1-Enter Win10 and open a cmd prompt as admin.

2-Change to shared disk partition (slice).

3-Run "chkdsk"

4- "shutdown" or "restart" and select Ubuntu from dual boot.

Should work now. I had this problem when I did a Word 2013 save on the data slice.

I re-saved the file from WIN10 Word 2013. Problem disappeared. Next time I used the "chkdsk" method. It reports no errors, but resets "something" that allows mount to work in Ubuntu.
