    Angry SD Card - cannot write to
    I have been transferring photos from camera and wife's computer to my iMac.

    I am now unable to erase the cards after the transfer has taken place.

    The lock slide on the card has not been moved, it can still be erased on the wife's MBA

    Any ideas as to what is going on here? Are the SD slots on the iMac prone to failure?

    Was working okay, then all of a sudden I was unable to format or erase the card.

    Hi Dave - not sure that I can help w/o some further information - first, when you removed the SD card from your iMac, did you eject it properly in Finder? If not, that can be an issue. Second, do other SD cards work in your computer, i.e. may be a problem w/ that specific card?

    Plus, please provide more information about your computer (e.g. model/year & OS X installed) - if you have used the SD slot a lot, then possibly the contacts have been contaminated - a few gentle shots of compressed air might help?

    I'll stop there and let you respond - Dave

    Also, you best bet is to format in the camera. At least that's been my experience.

    Thanks to you both.

    If I am using it in the camera that is where I format it. If I am using it to transfer photos or send to another OSX user, I like to format on the iMac.

    The card was ejected in the correct manner. NO SD card can be written to.

    I raised the matter at the Apple Store yesterday and they had not heard of this problem. Advised to bring it in, which I will do in the near future.

    Thanks once again

    Dave, may I suggest you try the SD Card Formatter - it's by the people, who actually developed the standard.

    G'day Dave,
    The issue here is not the formatting of the card. I have other ways to do that.

    The issue is that the iMac has all of a sudden stopped allowing anything to be written through the SD Card slot.

    That is my issue.

    Thanks all the same

    Do you have it locked on the SD card? Or when you formatted the card do you have it so other computers can't make changes?

    Can the reader read SD cards?
