You're SD card must be formatted to FAT32 format to work in the BoneView card reader. This is the #1 solution to folks getting errors on the iFlash Drive HD app.
- 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.
