Does anyone know exactly what goes on in the ``Checking Media'' phase of connecting with emplode?

I'm trying to get this RAID stuff to work, and I've got a mounted RAID set, but, for whatever reason, it fails the ``Checking Media'' step, and will never connect. It's the same over USB, Serial, and Ethernet.

Does the player usually recieve a restart code (``Restart code received'' from the serial console) at this point, after fscks have been performed?

Is it possible that it's actually failing the next step and emplode is misreporting it?

I know this has all been brought up before, but I obviously don't have the recourse to just reinit the player to solve it.
