Another point: When I say that a READ(10) fails, it does NOT mean that the command execution itself fails. Everything works as if the command exectution succeeds, but the resulting buffer contains garbage (i.e. not only 1 or 2 bytes differs) > > - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
