Unfortunately, i’ve been having quite the amount of issues with My Book Pro.
I had to send it in last month to be repaired as it was constantly re-mirroring my data. I finally have had the chance to use it and I’ve swapped out the 8tb drives for two new 6tb drives to start backing up new content. Drive utilities is not giving me the option to configure the drives. It is currently stating that the bays are empty. Although, with the 8tb drives, there seem to be no issues.
If anyone has any insight, that would be great!
