NTFS Volume Has No SecurityTab

[W]

I have an NTFS volume that is inaccessible. Logged in as administrator, I
right click on Properties for the volume and the Security tab is simply
missing.

I ran CHKDSK and the volume is fine and has no errors.

How do I investigate this further and recover the volume?

I just discovered the reason for this problem, but it leads to a new
question. I issued this command:

runas /user:administrator "cmd /k explorer.scf"

and it runs, but the explorer application runs in a normal user context.
Why? To contrast this command correctly starts explorer in the context of
the user specified in the runas command:

runas /user:administrator "cmd /k explorer.exe"
