A quick bit of research gives me two obvious sources for your problem. There may be more but these should be easy to identify or eliminate. The first is that the CF card could be a CFast card, designed for extremely fast read/write speeds and needing a card reader cabable of the specification. Second is the file system of the card. FAT32 file system can only create or read a single file up to 4GB minus one byte (now I know why my GoPro video files get split into multiple smaller files for a single long shot) and if your friend shot video with his Canon, or wanted to future-proof himself for the possibility then the card or its filing system could be beyond FAT32 spec.
So, have you tried connecting the camera to your iMac with an older/smaller CF card that is definitely FAT32? If it's a card compatibility issue, then your friend would have already catered for the problem, but you apparently haven't. regards, Anthony On 17 November 2012 17:20, Larry Colen <l...@red4est.com> wrote: > The widow of my friend who passed away from cancer last year asked me to > teach her how to use his Canon 5DmkII.
