How to format any SD card to 2GB
Posted: Sat May 30, 2015 9:09 pm
Hello all
Came across this very useful page today. It tells you how you can format bigger than 2GB SD cards down to 2GB
Do not use this information if you do not know the meaning of disk / volume. You can format your hard drive if you are not careful. Use on your own risk !!

Before starting, please remember that you can seriously mess things up if you make a mistake using command line disk management. Please make 150% sure you are selecting the correct disk so you don’t format your hard drive. You are solely responsible for anything that happens as a result of using this code
Instructions for reducing the partition size of a compact flash (CF) card:
Open a command Window (Windows-> Start -> cmd)
Type diskpart
A new window will open up with a “diskpart>” prompt
list disk
select disk n (where n is the number of your CF card)
list volume
select volume n (where n is the number of CF card volume)
clean all (this completely reformats the disk – it will take a while and appear to hang but be patient)
create partition primary (this gives the newly formated CF card a partition so it can be resized)
shrink querymax
This will tell you how much space is currently on available on your CF card. Subtract this from the filesize in MB you want for the final disk than add 1.
For my 4GB disk, shrink querymax returns:
“The maximum number of reclaimable bytes is: 3824MB”
I wanted a final disk size of 2GB which a google search told me is 1954MB so 3824 – 1954 + 1= 1871
shrink desired = 1871 (This tells diskpart to try and shrink the disk by 1871 MB)
Now that the disk is the right size, you can format the partition…
format fs=fat label=”volumelabel”
