While I never tested it myself, I suspect if you "protect" some photos (such a option is available on *ist DS) they won't be deleted with "Delete All", but will be deleted if you were to format the card. What I've tried, however, is when I have other, non-Pentax files on the card, *ist DS deletes them if I do "Delete All". I format the card every time, even though I suspect it is a superstition. Once with a DS, once with an old point-n-shoot Kodak, I had strange situations when a single file had problem being read after I was writing files to the card (SD and CF, respectively) on a computer, via card reader. I wrote to a card many times after without a problem, but that was enough for me to have formatting as a part of the routine. P. J.

I've never had to do an initial format on any SD or CF card. Don't mix two things: formatting the card (which erases FAT information) and initializing the card for the camera needs (which creates camera-specific directories on the card). When you tell camera to "Format", both things happen. When you get a brand-new card, it is already formatted. The camera just creates its directories. (AFAIK, this happens when it records the first image, not when you just pop it in, - at least in the cameras I've used.) While I've never tried it, - I suspect if you format card in your computer to any other file system, say NTFS, - and pop it into the camera, and try to shoot, - it won't reformat the card by itself.
