That's the joy of trying to support a nearly infinite number of hardware combinations that are all supposedly compatible. I personally have never had StreetDeck crash requiring a reinstall and I have been a user since before it was called StreetDeck or this forum existed (a coincidence that Chuck drives a G35 coupe helped). I did quickly learn to adopt the exact same hardware platform that they were using for testing (a MB896 motherboard - at the time that's what it was anyway).

To the OP, the Xenarc 700TSV does have this functionality - not sure that helps you out but perhaps you could ask Lilliput about their claim.

In terms of protecting a good SD install, using something like Norton Ghost and keeping an image offline (i.e. backup), seems like a prudent thing to do given the history.
