Until recently I had a Pi 5 set up to boot from a Sandisk external portable SSD (1 TB). This Pi 5 is intended to be my backup PC, perhaps even primary soon, and I had been using rsync to update files in the home directory (only). It worked until this morning's update, when the Pi 5 would no longer boot from it. What I saw on the Pi 5 was a non-blinking green LED, a non-blinking cursor in the upper left of my monitor, and the fan continuously running. [the Pi 5 boots fine from microSD]
As there was a new (11/19/24) version of Pi OS since I last imaged the SSD, I decided to re-image it and then, if that worked, re-copy my home directory over to it. Unfortuantely Raspberry Pi Imager does not see the external SSD as storage, even though it's connected by USB to my desktop computer. My desktop computer sees it.
So I re-imaged a microSD card, booted from that, then used SD Card Copier to copy the microSD card over to my SSD - using the Pi 5. That worked (FWIW I did select "create new UUIDs" for the SSD]. But the Pi 5 still would not boot from that SSD alone (when the microSD card was pulled from the Pi after shutdown - and flipping the switch at the power strip, for good measure). The symptoms were the same - solid green LED, solid white underscore on the monitor, and fan running. No change after a couple minutes.
My goal is to boot from this external SSD, as it could do before. Ideally I could continue to use rsync and backup my /home files to the SSD as well, so that if my main desktop conks out, it would be almost seamless to go to the Pi. [I'd still have configure Claws and some other things but my files would be there].
I'd be very appreciative for troubleshooting suggestions. Thank you
