If you want to corrupt a file on purpose (for whatever reason) there are some easy tricks.
Staging File Corruption
Ever seen the show Halt and Catch Fire? It’s a show about the computing boom of the 80’s and in the show the main protagonist makes it look like some floppy disks with important data has gone bust – only to get some PR. What I want to say is, that sometimes it can be quite handy to stage a file corruption for your own purposes. Just keep in mind, it’s a lot more honest to admit that you missed the deadline on something than try to stage something. In most cases, honesty will be rewarded!
