Is the media creation date stored in the "Volume Set Identifier"? I want to know the burn dates of my mastered BD-R media

[AlbertEinstein]

I'd like to know if the media creation date is stored in the "Volume Set Identifier" by chance and if so, is it a date and time, just a date, and how many characters do I need to convert it to an actual operating system date and time?

I know the log file stores enough data to possibly get it from there but let's pretend that got deleted by accident or corrupted. And I wanna get it from the media itself. Is this possible?

I don't know this for sure, but I don't think there's any metadata burned to a disc by ImgBurn that tells when it was written.  The closest you can probably get is to check the date/time stamps on files on the media and you might get an idea.

 

One thing I do when Building an ISO is put a folder in the root directory with the current date to let me know when it was created.

Yes, something along those lines will work, if, he doesn't use a date/time stamp in that Volume Set Identifier. I just had another idea also. There are 5 fields you can populate with data on the "Labels" tab called "Volume Identifiers". One of them is called "System" so I could just generate a date/time and cut'n'paste into that field. But, reading those fields would only be easy using ImgBurn, I imagine. So.....maybe a text file with the most recent date/time in the root of the DISC as you suggested. Even in the volume label itself if you don't need the full 128 ASCII characters that a UDF label provides. Just kicking around some ideas. Or I could just go old skhool and pickup a sharpie after the burn and....you get the idea!  I've actually done this before on a few platters.

And you could, if you've got spare Label characters, put the date in there.

Yes, in the volume label, unless you were referring to something else. Just depends on how many similar or different things I'm burning onto a specific BD-R disc I guess.

Yeah, the Volume Label.  I couldn't think of its name at the time.

Still, GUIDs on Windows systems always include the date/time because it's one of the things that changes constantly and, therefore, imparts uniqueness when things need to be this way. A volume set identifier would need to be unique as well so there's a good chance the developer uses a date/time as "part of" the volume set identifier.
