Windows was unable to complete the format

Hi, you can just format your SD card by Command Prompt :

1. Insert the USB Flash drive into your laptop or computer; wait until it will be detected.

2: Open Command Prompt by following this flow: Start →Accessories →Command Prompt or Start → Run → type “cmd” → Enter

3: Assuming your USB flash drive is assigned the letter “F”: type the following command in the Command Prompt with the following:

format F: /fs:FAT32

If you would like to convert the file system into NTFS, FAT, exFAT, just change FAT32 to the target file system.

Step 4: To continue or stop the formatting process, press Y (for Yes) or N (for No).

I think it’s no need to use the program, it’s not safe sometimes, you can just use the command on pc to complete your format.
