That can take some time if the card has a lot of books. If the cards share contents, such as you copied the books from one card to another and added more books, it should treat it as the same card and only process the differences. But, I haven't tried this.

The above is based on experimentation with my Touch and Glo over all the different firmware versions. The above is what the current state seems to be. As the firmware is common between the devices, I expect the Aura HD to work in the same way.
Thanks for the warning. Looks like it might be better to stick to 32GB cards, along with not mixing manga and ebooks on the same card. Manga is bigger so 32GB (~30GiB formatted) would hold roughly 600 volumes (at an average of 50MiB/volume) so I'm thinking it wouldn't be too awful. How does thumbnail generation work? Does it do it when you insert a new card? Because I'm thinking that'll be the most CPU intensive/time consuming given manga tend not to have metadata thus, there's less data that needs to be processed compared to a normal epub ebook.

Meh, too much hassle. Part of the reason I prefer using microSD cards is so I don't have to connect my devices to the computer.
