There is no need to format because we write complete disk image to a USB stick/SD card. Any data on a device is overwritten.
But you can use SDFormatter tool to remove both partitions and create only one big one when you don't need this device for libreelec.
Thanks. Makes sense
I see that multiple instances can be opened using the same image to write to 2 or more SD's at the same time.
That helps me a lot.
When opening the Tool it remembers my last settings in Step 1
When selecting the image file in step 2 the text in step 1 goes blank.
It does however remember the settings and ypu can safely continue to write the image.
When attempting to re-select the settings in step 1 the image selected in step 2 goes blank?
Using windows 10
Guessing their will be updates for bug fixes soon
