I have bought a refurb SanDisk Extreme compact flash 32gb UDMA7 and when I press record, I get an error message 'involid operation'. I have closed the doors, Does anyone know if these cards are compatible (they appear to be on the web) and if it is not the cards, then what it might be?<BR /><BR />Many thanks,<BR /><BR />John</P> Mon, 14 Apr 2025 12:58:35 GMT https://community.usa.canon.com/t5/Professional-Video/XF100-invalid-operation/m-p/544577#M5094 John_Page 2025-04-14T12:58:35Z https://community.usa.canon.com/t5/Professional-Video/XF100-invalid-operation/m-p/544729#M5095 <P>Did you format the card in the camera, which you need to do, before trying to use it?</P> Tue, 15 Apr 2025 12:22:36 GMT https://community.usa.canon.com/t5/Professional-Video/XF100-invalid-operation/m-p/544729#M5095 IamintheUK 2025-04-15T12:22:36Z
