Thanks for making this point, it made me realize that I had different assumption than what you use in your reasoning. I assumed that when writes to a USB device fail due to a temporary disconnection, the kernel can actually recognize that a write error happened. So are you saying that a write error due to USB problems can go completely unnoticed? That seems very strange to me; are USB drives really that unreliable or is that some software limitation?
