I've asked M support directly as the dealer I purchased the MD600 from no longer carries Meridian.

I have a QNAP NAS, but I also have a purpose-built (and bought) appliance in the form of a Meridian MD600 that's 1.5 yrs old and that cost me several thousand dollars. I'm not ready to experiment with a new plugin or to give up on the storage capabilities of the MD600
