Solar flares and even the occasional random neutron particle hitting your equipment can cause some weird issues. If its just a one time occurrence and it doesn’t happen again, I wouldn’t worry too much about it.

You could make a document describing what each set of data is, if its useful to anyone but yourself, or if its safe to delete. You could offer suggestions of what to do with each set. I think of it as a treasure map that you leave behind. Maybe they will be interested in it, maybe they will pass it on to someone else.
