UAC problems - set up one user for drive

[badderjet 181]

Hello,

recently Win10 Pro started to act up and would not let me delete files in my very own folders. Never had problems to far. Let me say when I set up Win10 I created an Admin account and a user account, the one I am using (it's just a single-user PC).

I have drive C as the system drive (SSD) and D for files and storage (HDD). I would want the user account to have access to the D drive. So after the above problems arised I tried to change the UAC settings for drive D, but I am having problems. Whenever I try to update the settings a little popup window appears and it runs through all the files on the drive, obviously applying the settings to all files. When it gets to the hidden System Volume Information folder, the process fails and I'm really not sure if it's the right way I'm going.

Also, after messing around and again logging into the user account, it tells me the Recycle Bin on D was broken for whatever reason. So far I didn't change anything else so maybe there is still hope if someone could assist.

Can anyone help me out here? I would want the Admin and that one user account to have full access to the drive.

Thanks in advance.
