Years ago I was working with my Kn7000, I had just put in 2 hours on a nice set up. I started the save procedure,which I knew quite well, pressed all the needed buttons, and then press save.

I still have not forgotten the next few moments -- I press saved, waited, my wife said something to my about dinner -- so I shut the keyboard off. OUCH!!!

The SD card showed only numbers, all titles were gone. I could load them, that worked, but their were no names. So I started to load and rename, it took a long, long time.
