Recovering Data from a Failed Synology NAS

I woke up last Saturday morning to incessant beeping from the recently commissioned Synology DS414j. All four HDD lights were blinking furiously and the status light was glowing orange. The unit’s web UI was inaccessible. Left with no other option, I powered down the unit with a long press of the front panel power button and restarted it. This time around, the web UI was accessible, but I was presented with the dreaded message that there were no hard drives in the unit.

Perfect example of why RAID itself is not a backup.
