Brand new 8TB MyBook, repartitioned into 4 partitions. The one I’m using is formatted as MacOS Extended Journaled.
I have it on a Catalina 27" late 2012 iMac, it’s on a USB3.0 port per the Hardware Summary.
A backup is insanely slow. The first 500 MB took 15 minutes. Drive is not formatted as encrypted. (In a previous try the drive was formatted as encrypted. Backup timed out after 4GB and 24 hours.
What do I need to check or do to make this work like a disk drive, rather than a carrier pigeon?
