This is something I’ve thought about too. I have some rare items on old DVDs that should be preserved. I’d love to upload it to Archive.org, but I’m hesitant because I don’t know if personal identifiers get attached to the media.
If I use a program like MakeMKV to rip my DVD to a computer, how do I check the file if there’s any personal identifiers? I’m aware I can right click and pick “Remover Personal Information” or whatever in Windows, but is there anything else that would attach any hardware identifiers to it? I want to preserve some of these discs since they’re long out of print and the company that distributed it is no more and you can’t buy this anywhere. I just don’t want my uploads to be linked back to me.
