Hiall, I had an old 8 gb compact flash card lying around, and I have used that before also. Book courier says something about an error, but then just loads the card like nothing had been said before. This Is why I love book courier! -----Original Message----- From: bookcourier-bounce@xxxxxxxxxxxxx [mailto:bookcourier-bounce@xxxxxxxxxxxxx] On Behalf Of Brian Cairnie Sent: Tuesday, August 10, 2010 9:35 AM To: bookcourier@xxxxxxxxxxxxx Subject: [bookcourier] Re: Question About Memory Card Hi All, I've used 4 Gb cards on the bookcourier without any problems, although it does take a while to say something when you insert a 4 Gb card, so be patient.
