Yes, SBDP is activated with my key (not trial).
Well, my setup may be non-standard.
I have two 4TB drives that were added to a pool that was created in SBDPv2 within S2012E. This pool wasn't created in v1.3, it was created in v2.
I have the individual drive letters turned off (hidden drives), with the pool assigned drive-letter 'E'. Both drives are visible in diskmgmt.msc and online.
When I have time later today, I'll assign drive letters and check for the hidden folders.
Question: Would clicking the "Add drive to the pool" button corrupt the current data in any way?
