I do all kinds of file swapping, copying and moving, both within the device itself and between it and my desktop. I've never reformatted them since I got them. I wonder if you're better off formatting them with a desktop in a separate reader, rather than in the device itself? I've been seeing lots of complaints from people who've reformatted their cards, but I haven't seen much of that from people who don't do a lot of formats. I know that the old floppy diskettes always worked better if you left the factory format on them, and tended to have more problems (especially if you tried to use them in a different machine) if you formatted them. I realize that a lot of that was due to physical issues rather than strictly electronic ones, but maybe there's something else going on with the common VFAT implementation that is causing conflicts with the internal logic of the cards. By the way, I've only ever had one memory card fail in any device (a CompactFlash), and now that I think about it I believe it was the only one that I've ever actually reformatted. When I want to empty a card, I delete the files rather than doing a format. If you think about it, that's a lot less stressful for the card, since a delete only changes a few bytes per file, whereas a format does a lot more writing, even if it's a "quick" format. I don't even want to think about what may happen if you try to use one of the file wiping utilities on a flash card.
