Select the drive and click the Scan button. These solutions will definitely help you resolve this error now. Surprisingly to me, Windows Backup does recognize it, but not the much newer Seagate drive. Cocosenor Backup Tuner is such a backup tool that allows you to copy/clone/backup all files of your computer to (Seagate) external hard drives.
After this, immediately apply the External Hard Drive Recovery Tool, scan it and recover digital media files from it.
