Writing to SD card of unknown format causes catastrophic crash

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Stick an OSX (or un-?)formatted SD card in a V4 unit
2. Try to write something to it

System crashes with blank display and does not recover.

The code should be made robust enough such that is will not crash the rest of 
the system -- no matter what happens with the SD card.

This is also another demonstration of why I think a modular approach to new and 
enhanced features is better than having a single CPU do all the work. At the 
end of the day, we need to be confident that primary function -- control of 
your model -- is not sacrificed when some sub0-system bug takes out a CPU.
Watchdog timers can help as a last resort, but his fault demonstrates how even 
they can be averted.
