Nod. Note further down on this page backup and file recovery is listed. That is in progress. Interestingly enough I have seen kids pull the stick out at the wrong time and that does not see to correlate with the stick failures based on observation not strong data collection. I would like to someday have a really robust solution that could recover from that sort of catastrophic failure and even go through the washing machine. I think such is possible. Right now I'd be happy if sticks rarely failed during normal usage. > > > It seems that there are a large number of software components involved. > Each one would have to be considered.
