I’m upgrading from 2 “My Book Live Duo”, a few “3TB My Book USB3” and some HD from a desktop that died.
My new PR 4100 has 2 x 8TB drives set up as RAID 1. What I would like to do is use one of the spare bays to install random drives that already contain data and copy that data to the RAID 1 volume.
Is this possible, what RAID mode would I use, and would I loose and data on the current RAID 1 by changing modes? BTW, I use a mac if that matters. Thanks!
