# Why is finder asking to authenticate when copying to my external hard drive?

macOS Sierra 10.12.6 (MacBook Air)

I am trying to move a directory/folder from my local disk to an external hard drive. But I get an error that says:

To move "<your-folder>", click Authenticate.

But I do not see any button or link labeled Authenticate. Also, I read here there might be a solution involving right-clicking the destination drive then selecting Get Info button. However, there is nothing there I can click.

So how can I move this folder to my external drive?

### Step 1.

Here is where I get the error message after attempting to move the folder.

### Step 2.

The 'Get Info' window is no help.

• That is not an external hard drive... it seems to be a remote DVD burner that was found on another mac... Try taking another look, check disk utility, see if you find your hard drive... please send us the result from ‘diskutil list’ – bret7600 Sep 5 '17 at 14:01
