I have 2 x 3TB disks I've removed from a Synology NAS. When I try to mount these disks on OS X, they show as only having a single 800GB partition.
I've tried erasing in the Disk Util app, but it only finds and creates a new partition for the 800GB.
Repartitioning, erasing, repairing, all only see the disk as 800GB.
Any idea how to get these back to 3TB each? Both disks behave identically, and are WD RED disks WD30EFRX

What avenue to wipe this drive and set it up for new filesystem to be installed exist?
