I have Calibre 2.71 install in windows 10 build 14931.

when I open Calibre. it works fine.
when I plug in , Kobo Aura One, I can mount and update it's storage.

But, If I start Calibre with the Kobo mounted, windows blue screens with a FAT_FILE_SYSTEM error.
if I plug the Kobo in with Calibre running it also blue screens.

Has anybody else seen this. it seems similar to the "Windows Anniversary Update blue screens when an ereader is plugged in" issue
