I realized I bought that disk a year after I bought the router. It died when I came home from my honeymoon (same night) and my roommate was a streamer, so I replaced it with that disk. I had an SD card, coaxed it to life on that, bought a 120GB disk from Canada Computers, then an 8GB off Aliexpress. Put the 120GB in the set top box later.
So that card is almost 10-years-to-the-day old
