    Hi All

    I wonder if anyone can help me....

    I am experiencing an incredibly frustrating problem when copying files across to my macbook pro from my memory card reader.

    Whilst copying the files, the card reader is ejecting itself frequently with no intervention from myself (every 10 images or so). I get a warning message saying that the reader has not been ejected safely and then I get the following error message:

    The Finder can’t complete the operation because some data in “IMG_6218.CR2” can’t be read or written.
    (Error code -36)

    Any ideas what's prompting this? It has been fine up until last Sunday when it first started happening :(

    Many thanks in advance

    It's an odd problem, have you tried different SD cards? Or the same SD card in different computers? Maybe it's not the SD reader.

    Hi there

    Yes, it's happening on several different cards and when I tried the reader and card on a different computer (windows not mac) it was fine. I think it's the USB ports

    Any ideas...?

    Think I might need to go into an Apple Store

    card reader ejects

    I have the same problem. I have one card that does not even read anymore (doesn't show up on desktop/finder) and I just bought a new one that ejects in the middle of transfers or just after a few minutes of being mounted on the desktop. The old one used to eject just the same but now it just doesn't even come up anymore.

    USB/Firewire external HD work fine and don't eject. Any ideas?

    Macbook Pro 2.2 non-unibody.

    hi! had the exact same problem. talked to apple and realized my lexar memory card reader was too old and couldn't handle 64 bit which is what the new macbook pros work on. easiest fix is to buy a new memory card reader. if that's not the exact problem, the image maybe corrupted on the card, this sometimes happens to me as well, i fix it by putting the card back in the camera, locating on the computer where the computer stopped copying over the images, erase on the card the images (2 or 3) at and after the last image written, then reconnect the reader to the computer and try again. not ideal i understand, but the best fix i could think of. hope it helps!
