how to reformat external HD from APFS to Mac OS Extended (Journaled)?
I am trying to change format on a 2T Lacie portable HD from APFS to Mac OS Extended (Journaled). This is to use it as a backup HD for large Photos libraries pursuant to an instructive discussion on this forum.
But when in Disk Utility, I click on the 2T HD, and then on Erase, I only get 4 options to format and all of them are APFS formats, which is how disk is already formatted.
Don’t know if makes a difference, but the disk in partitioned, and contains backups and photos and other materials. I have saved all these elsewhere, expecting that reformatting will erase all of them.
So, how to I reformat disk as Mac OS Extended (Journaled)?
Thanks.
