Is your Seagate external hard drive locked on your Mac? It means that you have read-only permissions, so you can’t add or delete files on your hard drive. Your Mac also considers that the drive is encrypted and cannot access the contents in the drive until you decrypt the disk.

  • Scroll down the page to the Sharing and Permissions section and click the padlock icon.
  • If prompted, enter the password you have set for your hard drive.
