It is a good practice to format SD cards once in awhile to keep them clean and functioning smoothly. Many trail cams today allow you to format right inside the trail camera menu. Otherwise you can do this on a computer too.  Here is an example on a Windows based PC. Most of our card readers are capable of viewing most FAT style formats such as FAT32 (most common), and this is most recognizable in all trail cameras.  SD formats can get jumbled over several uses, so it really helps to re-format and clean this up regularly.

  1. It can be as simple as putting your SD card in a computer, going to "Start" selecting "Computer", right click on SD card, choose "format" and then FAT32 format.  (See images below).  I have other tools and methods as well if this one doesn't work for you.

You're all done! Move some photos back to your SD card and test in the BoneView on your iPhone/iPad. You should be able to click on the top right "External Storage" icon in the iFlash Drive HD app to view your photos from your SD card.
