“I got a Samsung Galaxy S5 and I was planning to transfer the 64GB SanDisk micro SD card from my Galaxy S4. I unmounted the SD card safely from my Galaxy S4, and put it into a SanDisk brand card reader. Then, connect it to my Windows 10 and try to use Windows Explorer to format with options exFAT. But I failed. The format program run for about an hour and it never completed the job. Is there any powerful SanDisk SD card formatter that can help me to format the SanDisk SD card to exFAT successfully? Thanks in advance.”M
