I just watched Jason's video on the Ultimate Raspberry Pi install.
I had a slightly different approach that worked a treat, and was a little simpler. I thought I'd share...
I had the Raspberry Pi 4, 8GB card installed in the Argon M.2 case just as Jason had in his video.
For SD card, I just shut down my Pi Zero W and grabbed the SD from that and put it in my Pi 4.
I popped on the bottom with a spanking new 256 GB SSD and added the USB jumper.
I booted the Pi 4, and it came up, thinking it was my Pi Zero. Not a problem.
I opened a terminal window and ran
sudo apt install rpi-imager
I then use the imager to install an OS onto the SSD:
I selected the Raspian 32-bit Desktop OS and the SSD card. Hit Write. It took only a few seconds.
I Shutdown the Pi 4 and then removed the SD card.
I reassembled the case with the SSD and USB jumper and booted up.
It automatically resized the partition to be the entire drive and installed the OS.
Done.
No need for gpartd.
Also, since I then ran the BAP script using the SSD, it was *fast*.
HTH, 73
