When your GoPro displays an "SD err" message on it's screen this means that it is having trouble communicating with your SD Card. To fix this please first check to see that your SD card is completely inserted into your device. Second, you can navigate to the settings menu on your GoPro followed by utilizing the trash icon to delete all files off of your card and reformat the card so that it can properly communicate with your GoPro. You can also perform this step by using the GoPro App. Be cautious however, make sure to save any files off of your SD Card to another device before you get to this step to ensure that you do not lose anything. After this you can close your settings menu and your camera should return to normal. If your GoPro still displays the "err" message after making sure all the files have been removed from your SD Card, you must have a compatibility issue with your SD Card and your GoPro.

When filming longer segments with any GoPro including the GoPro Hero3+ Silver Edition, it will disperse these extended videos into chunked up videos. No frames are lost in this process, but you will have to put them together in whatever video editor you are using so that your video will once again be a continuous stream. This is a completely normal thing when filming with a GoPro. Upon inserting a SD Card into the GoPro, it will use a storage system mainly called FAT32 and for bigger SD Cards FATex. These file systems are good because they are very compatible with all kinds of computers (keyword VERY). This entails that these file storage systems can only process files of a maximum size around 4 GB. Now a days this may not sound like much, but back in the 90's when FAT32 was invented that was more than anyone would ever need. Being so, when filming long segments with any GoPro it will break up your video at different time segments depending on what resolution you are filming in and/or what rate of frames...

When using a micro SD card, it will fragment over time no matter how much storage it has. This means that you can have no files on your SD card and yet this fragmenting will interrupt the high transfer rates required to film in such high resolutions. To fix this problem, you can reformat your SD card, giving you a completely blank SD card to work with. This should allow you to film in high resolutions. To reformat your SD card, delete all the files off of it, and reinsert it into your GoPro. This should fix any problems you have. For more information regarding this problem, see the link below.
