    1. i installed the img file from cm-10.1.3 with win32diskimager, all was well but when i removed the sd card and reinserted it into my computer it gave me the message “you need to format before you can use it” and it will not read it.


    2. Jesse: Something might have gone wrong. Try it again. Download the image file again. Check its MD5 hash if possible to make sure the download was done correctly. After writing using imager, make sure to unmount the card correctly. Sometimes the writes are buffered and not written to the SD card immediately.


    1. Zachary: Depending on what image you wrote to it, it might seem like the space has shrunk. After you are done, you can reformat the entire SD card back to a usable filesystem partition like FAT32 or ext3 using a partitioning tool like GParted on Linux.


    2. you can just format your sd card with disc manager if your using windows operating system, if linux just use GParted to format your sd card


  1. jesse I had that message before you have to check your sd adapter make sure the little grey slider is all the way down. if not you can’t write anything on the sd disk
