saying it can’t create the backup folder, so it’s keeping me from being able to use the drive for much more than a paper weight… Any assistance in a remedy to this situation would be much obliged… Thanks!!

Hi @jtrentvines,

With Big Sur, Apple has changed the function of Time Machine. It will prompt you to reformat the drive to APFS in order to use with Time Machine, and lock the drive for sole Time Machine use.
