    I am having problems with my SD card that I use in my macbook air for extra storage. I have a 64GB MicroSD card hooked up via a Nifty MiniDrive that I store all my music, videos and pictures on. Every time I plug in a USB device into a USB port on the laptop (whether it be a mouse or a USB thumb drive) the SD card disconnects and reconnects and I get the following message.

    Disk Not Ejected Properly
    Eject “Macintosh SD” before disconnecting or turning it off

    Does anyone else's macbook do this? I am worried about it corrupting my SD from it constantly disconnecting without safely ejecting the card first.

    Mine does the same thing

    EnchantedPlague, I found your post after I noticed the same behavior with my MacBook Air last night. I attached a USB micro SD card reader and got the message about disk not properly ejected. I thought it had to do with the card reader, but noticed it must be the Nifty after trying the card reader on my iMac with no message. This at least lets you know that you are not alone.

    I had the same problem with a 64GB SanDisk Ultra MicroSD in my Samsung Galaxy S4. I contacted SanDisk and they sent me a replacement. The replacement has worked flawlessly.
