Hey frostyandroid, try going to your Dropbox preferences > Account tab and press the Option/Alt key; this should bring up some additional options.

There should be a file system warning one, so try to enable that and then reconnect the drive to see if that helps.

        Hey again, frostyandroid! Can you tell me what’s the total capacity of the external drive you wish to back up to Dropbox? 

        Also, after checking your post again, I see that you mentioned this in your original post “I cannot get my external drive to show up in the "Add a backup" section of the Dropbox Backup”; you were referring to the Backups tab of your app preferences (that’s mentioned here), correct?
