Bought myself a brand new Seagate HDD (formatted in exFAT). I tried copying over a bunch of folders to back up (160 GB worth) and I am met with the below error message. This is strange, because there is absolutely nothing on the HDD. I tried reformatting it to Mac OS Extended (Journaled) thinking it would help since that format is optimized for Mac OS, but unfortunately, I am met with the same error message. How can I get around this? By the way this is on Big Sur.
