microSD car size after use

Product support

I have a 128GB card. After using it for an OS I am repurposing it for imaging. When I try to use it now it says there is only 255MB of space. I reformat it but it still says 255MB of space. The OS that was on it was only about 3GB. How come? Is the card ruined now?

Hi @sparkie259,
Welcome to Balena Forum! In order to debug the above situation, can you help with some more details:

  • What is the OS you are running the formatting from?
  • What is the command you use to format?

If you are running Linux, you can use fdisk utility to see how the space is partitioned on the card: $> sudo fdisk -l

I used balena on a windows laptop to flash Stellarmate onto the 128GB card. Right click on card and select format.
