I have a Windows 2019 Server that is not showing some of the drives and drive space correctly.
Within the Windows 2019 OS, some of the drive shows correctly and you can access them without issue; however, a few of the drives when clicked on deliver an error that the drives are not accessible. 
What is really strange about this is that when I access Disk Management, the drive shows both healthy and correctly.
But then to make matters even weirder, if I LIST VOLUME in Diskpart the H: drive shows healthy as well; however, if I perform a LIST DISK in DIskpart then the drive shows with 0 free space.

So, effectively, Diskpart sees that the drive is healthy and has free space and doesn't have free space at the same time. The Windows GUI sees that the drive is healthy and has free space and is also inaccessible at the same time.
I have never run into an issue like this and have tried troubleshooting this without success.
Does anyone have any suggestions please?
Thanks in advance for your assistance!
