I'm running a ND2700 with firmware 1.09. Now I bought a 64 GB SDXC card. I know that ND2700 is not supporting SDXC card, but there is an adapter provided be delock called Compact Flash Adapter for SDXC/SDHC/SD/MMC. Insersting the 65 GB SDXC into the adapter it is working well for my cardreaders, but not for the ND2700. ND2700 is comming up with the error 0x0015 unkown cf card. Since I know that die adapoter by delock is working on other card readers I have to ask if there are any ideas on your site how to proceed on this.
