I had heard about the Synology HD policy thing, but had forgotten when I ordered the drives. By the time they arrived, the need was pressing and I had no window to exchange the drives, so I had to just hack the damn system.
Now I have to go out of town to unhack the damn thing so I can be sure nothing I did interferes with future updates.
This is the polar opposite of the experience I was expecting. This foolishness cost me a lot of time and is about to cost more.
