The quick format did not work, just FYI ( : http://www.ridgecrop.demon.co.uk/guiformat.exe )
64GB Sandisk SDXC
Mine was running perfectly for about 3 months, no issues then all of a sudden last week it stopped saving files (any files) in my Samsung Note 3…I’ve tried formatting in the phone, now with SanDisk Adapter on my PC…this ■■■■■! Luckily I was able to copy all my files over to my PC prior…so once (hopefully) I do get the SD fixed I can reload the files
