+--- Thread: [PROBLEM] Copying SD Card 8.3.9 (/showthread.php?tid=6779)
Copying SD Card 8.3.9 - thomaschan - 08-02-2024
I had previously set up and configured 8.3.9 on a micro SD card and it had been working. I normally use my mobile phone to connect my Pi 4B with MoOde 8.3.9 via WiFi (AP generated by Pi 4B).
I copied all the files from the SD card to my notebook, then copied to another SD card.
However, my mobile phone cannot detect the SSID of the AP generated by Pi 4B (I suppose this copied SD card is identical to my original card with 8.3.9).
What have gone wrong?

probably some hidden files have not been copied...
You usually clone a boot drive/SD card, not copy its contents...

When you create a boot SD Card from a moode operating system (OS) image file the SD Card will contain a specific disk partition structure thats populated with the OS files and application files (moode). If you subsequently copy these files to another SD Card, that card will not have the required partition structure and thus will not be usable.
You will need to use the Pi Imager to make the second SD Card.
I assume it's for another Raspberry Pi, correct?
If you want to have the second SD Card be an identical copy of the first (to be used as a backup card) you would need to "clone" the card using a disk cloning application. You would also need to get a USB-SDCard adapter so you can plug the second card into the host computer USB port. The cloning process can take a long time depending on the size of the SD Card and typically the second card has to be the exact same size as the first.
I think the Raspberry Pi Desktop OS has a disk cloning application.
