With Windows, I go to my computer, right click on the SD card, go to format. It gives the option for fat32, exfat, nfts I think. Plus the option to quick format or format the longer way. I've tried all of them. The link you gave me brings me to a page with a bunch of programs to download. Sorry, I'm not real computer savvy. I tried another program, but it just kept giving me tons of pop up ads. Thanks for the help though.. I appreciate it.
I don't know what program you're using but it should be there somewhere. When I ran winblows I used this free formatting program:
I use EaseUS Partition Master (http://www.partition-tool.com/personal.htm) for all my formatting needs on my Windows 7 PC. It's super simple to use. I've used it to format my 2 64GB SanDisk Ultra Micro SDXC cards to FAT32 and I've never hit any issues. Just plug in your SD card to your computer, open up the program, right click on the sd card you want to reformat, select format (or reformat (I can't remember what it says)), select FAT32, and voila. It's super quick to (done in a matter of seconds).
