How to fix "The item can't be moved to the Trash because it can't be deleted" error Got this error:

The item XYZ can't be moved to the Trash because it can't be deleted.

Never seen this before. How to I enable it to be deleted?



File is stored on an SD card. 

Checked permissions. Says:
You can only read

Which I have also never seen.

Tried touch /Volumes/&lt;Name of SD Card&gt; and got the response: touch: /Volumes/&lt;Name of SD Card&gt;: Read-only file system
Found the issue. The Lock Switch was set to Lock. 

A client had sent me the SD card with video files. I didn't even think to check the lock switch when I loaded it up. 

So flipping that to unlock, and it fixed the error and the permissions.
