Will not auto-mount or stay connected on Mac High Sierra. If iTunes and Time Machine are both using it, forget it. Nothing but “already in use” errors. Everything seemed to work better on Sierra.
Worse, I'm down to 50 GB now out of 8 TB. I've been in RAID 1 mode, which is Mirrored. That means Drive 1 and Drive 2 are mirror images. But I just learned that if I were to change to Spanning or JBOD modes, *both* drives will be reformatted. That seems absurd! Only 1 drive should be reformatted and all my data should be preserved on the unaffected drive. If this is not supported? Where am I supposed to back up 8 TB without buying a second NAS?
