How do you completely wipe a SD card from a Raspberry Pi3

How do you completely wipe a SD card from a Raspberry Pi3 with Libreelec installed so I can use the card to install LE for Raspberry Pi 4 ?

I am using Linux Mint no matter what I do it does not deleted the files, I try to reinstall LibreELEC-RPi4.arm-9.95.4 using the card it installs but never boots.

Gut feeling is there is files from the older version of LE that is not getting removed during a SD format that is messing up the boot.

I try using the SD card formatter it formats the card but if you look at the card in Files all the files are still there on both partitions, go ahead and use the SD car creator and install the new image says ok try booting the card in the Pi4 and it never gets past the initial boot up screen.

Before someone ask I do not have windows on any thing here.

Thanks in advance.

It's possible your SD card is bad and turned out to 'read-only mode'.

If possible, test it under Windows machine with SD card reader, use DISKPART in command line ( How to use DiskPart to clean and format drive not working on Windows 10 | Windows Central ), reformat it with single NTFS partition and copy some files there. Then eject the SD card safely and put it again to test if it's working (the new files are still there) or not.

You may also use an USB key to install and run LE on RPi 4B instead of SD card.

Ok as I stated in my original post I DO NOT HAVE WINDOWS ON ANYTHING HERE!

I am sorry you wasted our time hopefully the Windows suggestion will help someone in the future.

Yup libreelec.tv does not want problems solved in a reasonable time frame.
