Also try to cat the complete disk and see where it stops. dd if=/dev/da0 of=/dev/null bs=131072 BTW: I'm sorry to say that if you stress certain kinds of memory sticks they will simply stop working due to poor software design inside the meory stick itself. It is usually a problem of the memory stick manufacturer. However there is a way to nice/throttle USB transfers now! And maybe it is an idea to try that. How fast are your memory sticks? --HPS
