I had a Sandisk micro SD to SD adapter that would move the slider to the locked position as it was inserted into the card reader. The same Sandisk card used in an old adapter I had of a different brand worked just fine.

If you have a GoPro, you can use it to reformat the card. (settings>erase>erase all/format) This worked for me after failed attempts to reformat using diskpart.exe and other reformatting tools.

It appears that I am having the same problem with my new sandisk 64 gb card as many other people are having. I guess I'll just have to return it to Amazon and try a different brand.

I was able to format my card eventually....
I had searched and tried many ways including formatting via command prompt, formatting through my android and formatting through windows.
When trying to format with windows it would only give me the option to format it at 27gig.
In my android device it said that it successfully formatted and appeared to 64gig. however when connecting to USB in window it was still only 27gig.
I finally got it to format using the DJI OSMO UHD camera whilst connected to a USB port with Windows 7. upon connecting to windows through the camera, windows prompted me to format it and it allowed the full 64gig to be formatted... That's it!
I hope it helps someone out as I was almost going to try and get sandisk to replace it.
