I have successfully borrowed books from my local library, loaded them directly onto my 650 via the Sony software, and have read them with no problems.
I have been able to load books I own directly to a formatted SD card, load the card into my reader, again with no problems.
Where I have issue is when trying to read a borrowed library book from an SD card. I am loading the borrowed books directly to the SD card via a card reader. When I install the SD card the borrowed titles appear but they will not open, giving me a DRM error message.
Is this standard with borrowed books or have I missed something? The card is formatted properly, the software recognizes the card, and I always properly eject the card before removing it.
