If i plug it to another port attached to the same controller it does a couple of without errors: dd bs=4096 count=400000 if=/dev/sda1 of=/dev/null I can mount the filesystem but i get the same (infinite?) "FAT Directory bread(block n) failed" loop. So i suppose the next thing to do is to format the pen again :) thank you, Riccardo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
