I have read with other cameras such as a Sony EX -1R that you are supposed to delete all clips rather than to format the card each time. I have the Canon XA20 and wonder of the Initialize SD card will have a bearing on the life of the SD card. Does Initialize reformat the card or just delete the clips?
What I am using is Sandisk Extreme 45B/sec 64 Gig cards. Anyone had a failure with an SD card with The XA Canon cameras?? In the past I have always shot in the relay mode. But after failure of an aftermarket card with a SonyPMW 320 I have begun to shoot in the back up mode with the XA20.

Thanks
