[TUTO] (Windows) Format a Micro SD card correctly
#1
Lightbulb 
Hello everyone,

Sometimes when you want to format a micro sd after flashing a bone it often happens that when you format the micro sd card the space reduces considerably so here is a simple trick and without software to have the original space Wink

1) [Image: icon.png]  Open command prompt (CMD)
In the start [Image: dd1b-win10-logo.jpg] menu

2) Type the following lines:

Code:
diskpart
Code:
list disk
Select your micro sd in general it must be disc 1
Code:
select disk=1

Code:
clean
Code:
convert mbr
Code:
create partition primary

Then now you just have to format your micro sd and the original size should be present. Smile

Thats a way without any additional software.

If you don't mind a download, you can use SD card formatter here:

Linux doesn't need such tools.

There's a rule to respect, leave the space for u-boot, which is not belonging to any partition. Otherwise you'll surrender to a non bootable condition.
Beside that, it should be there the u-boot or another boot loader. But for another boot loader I don't see any candidate.

The only possible problematic can be u-boot environment space. But again ... if garbage is there, defaults are use. If true data is there from before ... that one will be used. Bottom line. As I already said. No worries about anything Wink
