  to **readable** on a Kindle e-reader, 7th generation? I've mounted and unmounted the Kindle multiple times. The file is there, it's the correct size, it's readable from `Calibre` -- not sure what else I can do.
  
  There it is, on the Kindle. But, not getting picked up. Other `mobi` files are recognized and readable. But not this one.
  
  why?
