Windows 10: I don't have permission to access a partition in my system

One day I opened my computer and tried to access a partition on my system when i found this messageI've tried to access this partition from cmd as admin but I couldn't?Note: I don't know if this has something to do with this error but I dual boot Windows and Linux Note2: When I tried to list the content from cmd [dir D:\] it listed the files successfully

Partition permissions

Hi all.

I have a laptop and created a C partition with Windows and programs (and system, boot, etc) and a D partition with select user data (Documents, Downloads, Videos, Music, etc) folders, and various other files and folders.

I wanted to change the default permissions on the D drive, particularly because Windows gave excessive access to my and other users' data folders.

So, I logged in as administrator and gave SYSTEM and ADMINISTRATORS group (COMPUTER_NAME\ADMINISTRATORS) full control to the D partition as well as folders and files on it. It shows up as "Inherited" from NONE and "Applies To" "This Folder, Subfolders,
and Files".

But when I try to open the D partition in Explorer, I get an error that it's inaccessible and access is denied. When I right-click to check Properties and then Security, I see a message "you must have read permissions to view the properties of this object.
Click Advanced to continue".

When I click "Advanced" I have an option to click "Continue" to attempt the operation with Administrative permissions. And finally, when I click that it looks exactly how I think I want it.

Principals = "System" and "Computer_Name\Administrators", both "Access" = "Full Control", "Inherited" = "None", "Applies To" = "This folder, subfolders, and files"

When I check "Effective Access" for this account, I see all green checkboxes, limited by nothing.

I can add other permissions ("Authenticated Users", etc) and then I can access everything I need on D.

My questions:

1. Why can't I, using an account which is a member of the Administrators group and without adding other permissions, open the partition and view the folders, and files?
2. What's the best way to set the correct permissions for users directory at D:\Users? The way I see it System and Admins should have all access to everything while users can additionally access their respective user directories and everything below.

Thanks a lot, community!
