It's unfortunate that some times in life, we will lose some sort of electronic file that wasn't backed up enough. Here's my recent tale.. As I switched to fedora linux, I had backed up my files to a micro SD card. Well, forgetting to check the files had all copied over properly, I swiftly formatted my computer and installed Fedora, which runs ok and maybe I'll do a one week review or something, and as I went to restore files from the SD card,.. a good chunk of them were 0kb.. womp womp... lesson here, make sure all files are properly backed up and they are good copies.
