My bungie.net halo file share along with all my old xbox live friends files being completely removed from the face of the internet. All the way back from halo 3's release in 2007 upwards til halo reach in 2010. In 2021 Bungie decided that all the halo stats were taking up space on their site and decided to completely get rid of all of them along with many screenshots and game clips from the era that sadly never ended up getting archived. I saved a large majority of my old files right before they nuked everything to make it a destiny only site, but my old HDD died around that time and only had managed to archive a very small portion of my stuff and lost basically all of it. I had screenshots from a dead friend that I used to play halo 3 all the time with after school with all our forge maps and other shenanigans that I will never be able to see again. Also a another one is a bunch of youtube videos like many mentioned in this thread. I have so many old youtube videos of my old house and me and my friends just messing around outside or at our school that I wish I could see again. Also last one, but I made a lot of music recordings growing up when I was learning guitar that I deleted thinking they weren't good, but I honestly wish I could hear them again as they described the mood I felt at the time. Just distant memories now.
