I have a Boyue Likebook Mars with an external SD card on which I store the books that I load from Calibre. I've noticed this odd behavior from Calibre where it rescans the whole file system on the card each time I connect the device, taking anywhere from 10 to 25 minutes.

Calibre is on version 4.13 running on Ubuntu Linux, I've fiddled with the different options for metadata management and configured the device and SD card to scan only specific folders, but each connection still involves a full scan (at least, going by the "Found object <folder>" messages that show up for the fetching book list task in the jobs window).

Is there anything I can do to speed up this process?
