Meaning that spinrite can extract data that the drive itself in normal conditions cannot. This reasoning is sound. Remember that a drive is an analogue device, not a digital one (only the *output data* is digital). There is some doubt as to whether spinrite can even function in this wise with modern drives though. -- alan dot mckinnon at gmail dot com
