How to: format your SD card back to the original size (WINDOWS)

Picture of How to: format your SD card back to the original size (WINDOWS)
After writing any image with an OS for your raspberry pi, you may have notice that no matter the size of your SD card, windows can only recognize one partition with about 60 mb. If you try to format it in the Computer menu (righ-click on it and press format), it will only free the space in that partition, to have access to the full space you have two options (only one is needed):
- SIMPLE PROCESS: step 1 - SD Formatter
- ADVANCED PROCESS: step 2 - DiskPart

Step 1: SIMPLE PROCESS: SD Formatter

Picture of SIMPLE PROCESS: SD Formatter
1 - Download and install this software (from the SD card Organization) :
https://www.sdcard.org/downloads/formatter_4/eula_windows/SDFormatterv4.zip

2 - Open the program, and select the right drive (in my case is G:), after that just click "FORMAT"

3 - You have just formatted your SD card! CONGRATULATIONS

Step 2: ADVANCED PROCESS: DiskPart

1 - Go to the windows start button, write diskpart and press "enter"

2 - Wait a few seconds and write on this order:
- "list disk" - shows you the disks that are currently connected to the computer;
- "select disk X" - substitute x with the number of the disk
- "clean" - deletes all the data in the SD
- "create partition primary" - creates a partition in the sd 
- "format quick" - makes a quick format

3 - You have just formatted your SD card! CONGRATULATIONS

thanks for creating this! i have a stack of cheap sd cards that we're going to try to breathe a bit more life into them by trying this. otherwise, we might go toward making some cool accents for crafting projects.

Thanks a bunch to the person who made this! just saved an 8gb card from the trash :D

Have you tried both ways?
What is the error that it gives you?
Does the computer recognize the SD card? And what OS are you using?
