Formatting external drives
Hi, I've been a PC user almost exclusively and am still finding my way with my MacBook Pro, now updated to Big Sur.
With PCs, formatting external drives was a snap; with mac, not so much. At least not for me.
I chose the full format, meaning security options to make sure the data were gone, and MacOs Extended (journaled). This meant, to me, that the drive should have been completely empty at the end of the process, but for whatever it needed to keep the drive itself working.
Wrong. There is an unexplained 800 MB file--almost 1G--that I have yet to find any description of anywhere.
Does someone in this community know what it is, why it's necessary, and why I can't get rid of it?
Thank you so much!
