i had several time that when i like to create the clean install the SD looks to be locked Unmount because of the installation already on the SD .I have no idea why this is

I load than the umbunto-mate via etcher, if the SD is new it has no problem but after than i am not able to burn save back the backup img file or a clean umbunto mate install with etcher, it looks like write protected.
