How To Mount a Windows (NTFS) Filesystem When Hibernation is Preventing Access in Ubuntu

Ubuntu 2

In the world of dual-boot systems, it’s not uncommon to encounter issues when trying to access a Windows (NTFS) filesystem from Ubuntu. One such issue arises when Windows is in a hibernated state, preventing Ubuntu from mounting the NTFS partition. This article will guide you through the process of overcoming this hurdle.

Quick Answer

To mount a Windows (NTFS) filesystem when hibernation is preventing access in Ubuntu, you have several options. You can disable Fast Startup in Windows, properly restart Windows instead of shutting it down, mount the partition in read-only mode using the terminal, use the ntfsfix command to repair inconsistencies, or disable hibernation in Windows. Remember to back up important data before making any system changes.

Understanding the Issue

The root of this problem lies in a Windows feature called “Fast Startup” or hibernation. When you shut down a Windows system with this feature enabled, it doesn’t fully shut down. Instead, it saves the system state to a file called hiberfil.sys to allow for a quicker boot time. However, this means the NTFS partition is left in a state that Ubuntu can’t mount.

Solutions to Mount the Windows NTFS Filesystem

1. Disable Fast Startup in Windows

The most straightforward solution is to disable the Fast Startup feature in Windows. Here’s how:

  1. Boot into your Windows system.
  2. Navigate to Control Panel > Power Options.
  3. Click on “Choose what the power buttons do”.
  4. Click on “Change settings that are currently unavailable”.
  5. Uncheck the “Turn on fast startup” option.
  6. Save changes and restart your system.

2. Properly Restart Windows

If you don’t want to disable Fast Startup, you can avoid the issue by restarting Windows instead of shutting it down. A restart does not trigger the Fast Startup feature, ensuring a complete shutdown that allows Ubuntu to mount the NTFS partition.

3. Mount the Partition in Read-Only Mode

If you only need to read data from the NTFS partition, you can mount it in read-only mode using the terminal in Ubuntu. Here’s the command:

sudo mount -t ntfs-3g -o ro /dev/sdaX /media/windows

In this command, -t ntfs-3g specifies the filesystem type, -o ro sets the mount options to read-only, /dev/sdaX is the device to be mounted (replace X with your actual partition number), and /media/windows is the mount point.

4. Use the ntfsfix Command

The ntfsfix command in Ubuntu can repair some NTFS inconsistencies and schedule a consistency check on the next Windows boot. Here’s how to use it:

sudo ntfsfix /dev/sdXY

Replace /dev/sdXY with your actual partition. Note that this command doesn’t perform a full filesystem check, but it’s often enough to allow Ubuntu to mount the partition.

5. Disable Hibernation in Windows

As a last resort, you can disable hibernation in Windows. This will delete the hibernation file, but it will also cause the loss of any unsaved information in hibernated Windows programs. To disable hibernation:

  1. Boot into your Windows system.
  2. Open an elevated Command Prompt.
  3. Enter the command powercfg /h off.

Conclusion

While the inability to mount a Windows NTFS filesystem due to hibernation can be frustrating, the solutions outlined above should help you overcome this issue. Whether you choose to disable Fast Startup, restart Windows, mount in read-only mode, use the ntfsfix command, or disable hibernation entirely, remember to always back up important data before making system changes.

What is Fast Startup in Windows?

Fast Startup is a feature in Windows that allows for quicker boot times by saving the system state to a file called hiberfil.sys when the system is shut down. This feature is enabled by default in Windows.

Why can’t Ubuntu mount a Windows NTFS partition when Fast Startup is enabled?

When Fast Startup is enabled, the NTFS partition is left in a hibernated state, which prevents Ubuntu from mounting it. Ubuntu cannot safely access a hibernated NTFS partition.

Can I avoid the issue by simply restarting Windows instead of shutting it down?

Yes, restarting Windows instead of shutting it down can avoid the issue caused by Fast Startup. When you restart Windows, it does not trigger the Fast Startup feature, ensuring a complete shutdown that allows Ubuntu to mount the NTFS partition.

How can I mount the NTFS partition in read-only mode?

To mount the NTFS partition in read-only mode, you can use the following command in the terminal in Ubuntu:

sudo mount -t ntfs-3g -o ro /dev/sdaX /media/windows

Replace /dev/sdaX with the actual partition number and /media/windows with the desired mount point.

How can I use the `ntfsfix` command to resolve the issue?

The ntfsfix command in Ubuntu can repair some NTFS inconsistencies and schedule a consistency check on the next Windows boot. To use it, run the following command:

sudo ntfsfix /dev/sdXY

Replace /dev/sdXY with the actual partition.
