I've read an article about Japanese policeman that've lost a floppy disks with personal data of some Japanese men, it was a story from this January.
This data leak, due to obscurity and the volume was more of a joke in my country, than a serious news. I do however wonder, what it was back in the day? I've never heard of any large scale data leaks involving floppy disks, perhaps I'm too young.
