Hmmmm.... Using CF cards in my by now jurassic Nikon digital camera (bought 2001...
), I must say that I always format the card in the camera after transferring pics, and I have never encountered a problem, either when hooking the camera up to my (now defunct) desktop, or by slotting the card into my replacement, card-reader equipped laptop.
However, this formatting thread is interesting- I have just bought a new RS-MMC card, for use in my mobile (reason being I have GPS in my phone), and I have transferred various "countries" into the new RS-MMC card- There is no FORMAT function on the phone, I was unsure which option to pick from the PC, and the GPS manual is mute on the subject...
Data transferred, phone seems to recognise the maps, but I will have to see when actually on the move- Why is formatting so important? How is it different to "Select all" - "Delete"?
