HI,

I have a Synology 216j se NAS with two 4TB drives working a one 8TB drive. I have bought two 6TB drives and want to clone the same partitions with the data in them but the 4TB drives are not readable by OS X (with or without FUSE)

Is there a way to do this?
 
Solution
I'd do this in something like CloneZilla. https://clonezilla.org/
Even better get a secondary syno to do live replication to.
