Thanks for reply. I have since updated the OS, now on the latest version. I formatted the SD card to FAT32 as i had read as it is 64GB, the Z10 will not recognise 64gb unless it is this format. (now know this is incorrect)

Since updating, the problem is in part solved. I no longer get the error message, but the maximum file size using FAT32 is 4GB, limiting 1080p video to 40 mins or so. To get round this i have tried a different 32gb SD card formatted to exFAT. This card is recognised by the Z10, but it will not let me record video directly to it, only to the internal memory. The internal memory is only 16gb which is insufficient for my requirements.

Any ideas why i can't record direct to this SD card?

It is sandisk, class 10 32gb.

Thanks
