Awesome guide!
I did not want to install some unneeded “bloated software suite” just to partition a SD card, so I first tried Disk Management, but as you said it does not allow you to format as FAT32. (I am using Windows Seven Pro SP1 btw) Then I bit into the sour apple and tried the diskpart program. I carefully read through the commands and workings of it to be sure not to break my system. But I forgot to turn on the QUICK command, to get a fast partition, so I had to wait around an hour for my 64 GB card to be formated.

When it was done the diskpart program responded with an error message telling me that the volume was too big! Could it not at least have told be that before it started the format process! After some more research it turns out that the diskpart utility is from the Windows 2000/XP days and for some unknown reason it does not allow you to format a FAT32 partition larger than 32 GB. Windows 98 apparently does but my guess is that not that many people have a machine with that OS around anymore.

I read a little more about partition programs on a site where I trust the people are tech-savvy and saw MiniTool Partition Wizard getting recommended there as well and decided that it must be a good program. So now I am downloading it and would recommend anyone else with a card larger than 32 GB to do the same, unless you already have a non-Microsoft partition program installed on your system.

Thanks for the guide Dekay!
