Flatland: Another Perspective Mac OS
Flatlandspider said: I think that was more because they had to handle resource forks for backwards compatibility to Mac OS 9. This, by now irrelevant. The next thing now is. Select the Zoom tool in the Vanishing Point dialog box, and click or drag in the preview image to zoom in; hold down Alt (Windows) or Option (Mac OS), and click or drag to zoom out. Specify a magnification level in the Zoom text box at the bottom of the dialog box. Click the Plus sign (+) or Minus sign (-) button to zoom in or out, respectively. In Mac OS X 10.5 registering mount points for drives is dropped altogether. There is a workaround if Spotlight is running, since this application will occasionally try to update the file system identifier on a removable volume. This process is automatic and, if data on that volume was updated since last in a Mac OS X 10.5 machine, or the volume. 📕 Mac OS X and IOS Internals: To the Apple's Core, Volume 1 User Mode (2015) Philosophy 📕 Godel, escher, bach (1979) - Explores fundamental concepts of mathematics, symmetry and intelligence and how they interlink.
I need to format my external hard drive for use with (encrypted) Time Machine backups -AND- simultaneously for additional storage (password protected) - without having to partition the drive.
That was never a good idea, and with Big Sur I have reason to believe you may no longer do that.
For what it's worth your experience is identical to mine. Once you connect a previously unused backup drive and designate it for Time Machine backups, TM owns it. From TM's security perspective that's a good thing.
I have a separate, exact same external hard drive on another Mac running Big Sur which was formatted in macOS Catalina prior to the Big Sur upgrade, and I can use that drive seamlessly for both encrypted Time Machine Backups as well as for additional storage - encrypted and password protected - without having to partition it.
Same here. Time Machine will respect what you did with that drive and its files and won't change any of that.
Is there any third party application or utility I can use to still achieve reformatting my drive to Mac OS Extended (Journaled, Encrypted), or am I stuck with my current dilemma?

Not to my knowledge, and I would be reluctant to use anything like that in conjunction with Time Machine. Its primary purpose is reliability and the only way to assure that is to let it work.
