<p>I have resolved the issue simply by changing the card reader. The last time I used the 'bad' reader, the 7D could not even format the card. Took it to a camera store and they formatted it in a Nikon ok, then the 7D could reformat. Old card reader (Zeikos 57 in 1) is now in the trash and has been successfully replaced by a ProMaster. Hopefully it continues to work without issue. Thanks for all of the responses.</p>

<p>When I mount the reader on the Mac using only SnowLeopard (no other applications) the GetInfo indicates that it is formatted as MS-DOS (FAT32). So is it changing the format from the CanonOS?</p>

<p>I am using a Mac with Snow Leopard, and just doing a Finder copy. And I do eject the card when done. I am not deleting the files from the card...I like to keep them there as a backup if I am on the road. But I can't since I can't shoot any more photos without reformatting.</p>

<p >I have an SanDisk Extreme CF card and a Canon 7D camera. I am off loading my photos to my computer via a Zeikos 57 in 1 memory card reader. Reading the images works great. However when I put the card back into the camera it is not recognized and say I must reformat the card. Reformatting works fine. But my question is what is happening here? Should I get a different card reader?</p>

<p>I want to be able to fire my speedlite 430 wirelessly from my 7D without firing the built-in flash. But each time I shoot it fires BOTH the built-in flash and the 430. How can I get it to only fire the 430 wirelessly?<br>

Under flash controls / wireless func...I have selected the icon which displays only the external flash (not either of the ones with two icons), as indicated on pg20 of the 7D manual.<br>

Thanks in advance.<br>
