    Hi there people I am pretty much computer illiterate so please be a little patient with me if I'm being silly but>>>>>>

    I have this issue when I insert my (SanDisk) micro sd card "The disk you inserted was not readable by this computer." with no option to "initialise" just "ignore" and "eject".

    I don't know if it makes any difference but it was last in my GoPro Hero 3 Black edition.

    Any help would be really appreciated.

    Thank you

    Joel

    Hi , please tell us what version of OS X are you running ( upper left corner of your desktop - apple - About this Mac ) e.g. 10.6 , 10.7 ...And which MacBook do you have. You should look at your memory card too , there's a capacity written on it - 32,64gb...

    OK , it seems to be not a problem with hardware or software. The next thing - check what kind of filesystem is on the SD card ( disk utility - your card - filesystem )

    Yes like that.So the partition (card) is currently unformatted with no filesystem and no files on it.If are you sure you dont have any files or videos on it recorded by the camera etc. , go to disk utility , click (highlight) the card , go to erase tab ,click on the format and select MS-DOS(FAT) and then erase.This should be working and you will see your card as a usual drive in finder.

    Your card is unformatted, that is why it cannot be read.
    It is also 32GB not 64GB.
    Go to Spotlight (the search bar top right of your screen.
    Type Disk Utility and then click on it in the list that appears.
    With your SDXC card inserted you will see it on the left of the screen that opens.
    Click on the card, then choose the erase tab on the right.
    If you want to be able to read and write to it on a Windows machine as well as Mac choose MS-Dos FAT from the format menu.
    Then click erase (bottom right).
    Once it has finished you will be able to put files on it.

    it is definitely a 64gb card as it states on the card its self.

    There are some videos and pictures on the card from my recent holiday and when the card is highlighted the erase option and several of the others are sort of "greyed" out so I can't select them.

    thanks

    There is a simillar thread on the Apple support forum - https://discussions.apple.com/message/24313328#24313328 - (user Andy Beckett) and maybe it is caused by OS X version - 10.9(theoretically supports ExFAT) has this issue with GoPro and its filesystem.You can try to read the card on another device or with a different version of OS (10.8 would be ideal) or with a Windows PC.

    Relabelled cards are pretty rife in some places (64GB label on a 32GB card). Does the Go Pro see it as a 64GB card?

    That shows it as only 32MB:confused:
    Just out of interest how much did you pay for it?
