This is very curious... I'm now wondering if it wasn't a full 1M wipe. But instead something more like
# dd if=/dev/zero of=/dev/md3 bs=446 count=1
or maybe the Synology Nas tried to restore some of the boot sector when it I tried to do the repair on it?

Regardless; I just booted the NAS and did a quick 'history' to see if it would find the real command. Of course because /dev/md3 is gone... there's no history for my user account.

On a whim; I did the same command for the "Safe" 4TB drive that didn't receive the wipe. Not sure if it's of any value but here it is:
