Format SD card(update 10/20/2019

Step 1 & 2 is conbined using "SD CARD Formatter.exe"

Need to test if 64G sd card works the same. If 64G sd CDcard is formated to any formay beside fat32, then follow step 1 & 2.

1.Use SDformater to overwrite the sd card and restore the size back to 64g (57g)

Under Option, select Full Overwrite and Adjust Size on. This will take many minutes.

2. use command line

cd to fat32format directry

fat32format X: wher X is the drive letter

(Do not enter -Cn, the default works)

Instead of NOOB as in step 3, Use Etcher.exe make raspbian-buster.img into sd card.

3 copy extracted NOOB to sd card(files in directory)

4. boot from raspberrypi

5.Enable SSH
