It was a catchy line to grab your attention I am not convinced it was Filebox's fault. I know some cards die but I was not expecting a card to die during a read operation. Of course there was a hidden write operation too since I had a swap on that card and the most active culprit at the time was Filebox. But I agree blaming FB is unfair. Sorry.

FWIW, the card is totally dead. Debian cannot find it at all, N900 can but thinks it is 32MB instead of 8GB. Time to invest in a better card I reckon.
