When I try to change my Sharing & Permissions on a Seagate One Touch 4tb External Hard Drive, Finder says "This operation can't be completed because you don't have the necessary permission.

If it is used for Time Machine backups then TM "owns" that disk and you don't have permission to alter its contents.
If it is not used for TM backups then you can reformat it using Disk Utility, and you will have permission to alter its contents.

Before you do that Get Info for that drive and determine if there is an "Ignore ownership on this volume" checkbox. If there is, click the "lock" icon to authenticate, and select it.
That option will not even appear on TM backup drives.
I checked. It's not, so I'll reformat the drive. Thanks for the feedback.
