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.
