When you connect a previously used hard drive to a new or different computer, either as an internal or external drive, you will not have ownership of that drive. When you try to view, add or delete files on that drive, you will get an error message stating: “E:\ is not accessible. Access is denied.” Your drive letter may be different, but you get the idea.
- In Windows Explorer, right-click on the drive you want to take
ownership of, then select “Properties” from drop-down menu.
- Click on the “Security” tab.
- Click on the “Advanced” button.
- Click on the “Owner” tab in Advanced Security Settings.
- Click on the “Edit” Button.
- Click on the “Other users or groups” button.
- Under “Object Types”, uncheck everything except “Users”, then click on OK.
- Click on the “Advanced” button.
- Click on the “Find Now” button.
- Under “Search Results”, click the “user name” that you log into windows with, then click OK.
- Verify the correct user name in the object window, then press OK.
- Place a check mark in front of “Replace owner on subcontainters and objects”.
- You will see a warning message stating that “All permissions will be replaced…”. This is normal. Click on “Yes”.
- A status window will show file permissions being rapidly replaced.
- If you see an error message saying “Access is denied”, it’s not a problem. That message only refers to a specific system file that’s currently in use. You don’t need access to it anyway. Just click the “Continue” button.
- Click OK on the final Windows Security message.
Almost done.
In Windows Explorer, right-click on the drive you just took ownership of, then select “Properties” from the drop-down menu. Under “Properties”, click the “Security” tab. You should see your user name in the “Group or user names” window. Click on the user name to highlight it, then click on the “Edit” button.
Under the “Allow” column, place a check mark in the box for “Full Control”, then click on the “OK” button.
The hard drive should now show up in Windows Explorer with data about its size and free space. You should be able to click on it, then click on any directory, then add, delete or modify files as needed.
Done!
