If you use your SDXC to make a recovery image, drive. However, it will likely be reformatted to a fraction of its specified capacity. When you decide to return your SDXC card to normal service, you cannot use the Windows built-in Format options to return it to original (like my SanDisk 128GB), but instead use the SD Formatter free formatter from here. This utility will return it to the maximum possible capacity.If found a post by Colorado with a link to a format utility that returned my SD to it's full capacity!
WHEW!
