SD card formatting issues

    There's been various discussion about SD card formatting problems, including
    a thread in this group a year ago, but I haven't seen any definitive
    information. Can anyone give a pointer to this? Google finds only lots of
    personal experiences and "this should happen".

    My own experience is that I put a new SD card in a Panasonic FZ3 and took
    some test shots without remembering to format the card first. The card
    worked fine in the camera and in Jessop's card slot but would not read in a
    card reader on my PC running Win XP. In fact the PC did eventually find
    folders and files but could not do anything useful with them. I formatted
    the card as FAT32 in the PC (knowing no better at the time) and it then
    worked fine in the PC. But then the Panasonic FZ3 did not recognise the
    card at all and would not even re-format it. However another camera
    re-formatted it without problems and it would then work in the FZ3 and also
    in my card reader.

    So, given that the card was formatted wrongly for the camera, why should
    this stop it being re-formatted correctly? This seems to be a fairly common
    problem with SD cards but does not usually happen with disk drives etc. It
    seems to me that SD is rather fussy. I don't remember having this problem
    with CF.

    I have had trouble with new SD cards and getting them to read in a card
    reader. However, this problem seemed to disappear after a few
    insertions. I suspect there may be a preservative coating on the card
    which a not quite tight enough slot isn't penetrating the first few
    times. Try slotting troublesome cards in and out a few times.

    I don't think that was the trouble in this case. The card worked perfectly
    in the camera and a card slot in another PC. Also it worked as soon as I
    re-formatted it with my PC. Then in the FZ3 it worked as soon as it had
    been re-formatted in another camera. The symptoms clearly point to a
    software "feature".

    It may seem that way, but I had similar problems with a new card some
    time ago, and a few insertions in devices with tight slots, such as my
    camera, and the card reader built into my wife's computer. Soon it
    worked find on my card reader with a much less tight slot. As long as
    it is now working, I guess it doesn't matter much.
