Cannot view free space of mounted volume in Windows 10

If a directory is a mounted volume and I ask for properties, it will show free space in Windows 7. However, after I upgraded my computer to Windows 10 Pro, it is not working at all. I open the disk management and go to properties of the mounted partition, it shows 0 free space and 0 used space. I can use any apps or software and access files on that disk. How can I resolve the problem?

The disk store about 1.5 TB of data, while I am bale to watch video and view photos from there. So the volume is not corrupted. I boot the PC into safe mode and I still face the same issue. All previous information are broken after the upgraded process.

Within the events tool, it lists the “device migrated; device configured (disk.inf) device started (disk).” It seems that the volume doesn’t examine. I remounted in a new folder and it is fail to do that. Then I use the Hard Disk Sentinel Pro and it reports all volumes are 100% health.

You could try the workaround to verify how full a mounted volume is in the meantime in Windows 10.
* From your desktop, click on the Start button, open Control Panel, go to System and Security > Administrative Tools, and then double-click Computer Management.
* In the left pane, select Disk Management under Storage.
* Click on the volume that you want to view. And the section at the top will show the free space and percentage of space remaining. I mount the drive as a folder on other computer and the tip works.

The Mac also can help you fix the issue. Sometimes I need to share the resource from the Windows 10 to my Mac. Once I connect my MacBook running macOS 10.13.3, the Mac system provide the correct information about the available free space on that drive.
