according to diskpart, its not being recognized at all. not promising.
it'd be similar to unlugging a hdd that is running.. cutting power mid operation can cause hardware failures.
quick question - do you have a phone that can take micro sd cards for storage? could try seeing if your phone recognizes it (just a different operating system, so possible) OR you could boot from a linux live usb and see if it will recognize the sd card(s).
Although, if a BRAND NEW one is not recognized by windows either, im very curious as to what could be causing that. Download the portable 64bit (under step 2) and extract to a folder. then plug in one of your sd cards. then launch "partitionwizard.exe" in that extracted folder. post a screenshot of what it detects.
