I bought a new Seagate BackupPlus portable drive and confirm it works on my PC, but when I attach it to MyCloud I get an error notification in screenshot below. I previously tried backing up to the old portable drive I had been using for backups, but the backup failed and I assumed it was a problem with that old portable drive. Not sure if the two problems are related, but hopeful someone here can at least help with the notification on the new drive. Thanks.
