D drive is read-only after windows 10 upgade

I'm trying to figure out why my D: drive is read only after updating to Windows 10. It is a separate hard drive and not a partition of another hard drive.

I do have bit locker installed but it is turned off and I never used it. I tried taking ownership, permissions, unchecking the read-only box, and more but still everything the folders become read-only again. I can open everything but just can't modify them.

I had the same issue going from Win7 to Win10. Here's how I solved it (requires administrator rights):

1. Right click the conflicting folder (or disk), go to Properties, then to the Security tab, and click on Advanced.

2. Change the owner so it becomes yours. You may want to check "Replace owner on subcontainers and objects" so its applied everywhere inside it.

3. Click OK, close the Properties dialog, and open it again.

4. From the Security tab, add your user to the permission list, allowing Full control. After applying the change you should have access to your files again.
