That's what I observed with the sharp unit, too. As the RH-1 is more friendly than the sharp unit regarding data structure access, I will try whether I can get a dump of all track info blocks an that unit. I have access to a RH-1 unit soon. > Assuming the above command is > correct - is it perhaps the case that "content_creation_date_and_time" > cannot be retrieved using a MZ-RH1? I'm afraid that it probably means that getting the date with the RH1 is not possible. You might want to try 05 instead of 04. 05 is last modified date, while 04 is original creation date.
