After 30 minute Library update...library is empty!

I'm missing something key here!!!

If you found that a usb flash drive worked but the SSD does not then the most likely cause is that your Pi cannot supply enough current to the ssd and once the resource/power intensive update happens the SSDdrops out.

This of course assumes your SSD is USB powered from the Pi.
Try a powered USB hub between the Pi and SSD

Right....I tried placing the SSD in it's own powered 'caddy'....same 3 seconds of update activity...then stops!
Good thought though!
Should the blue USB 3.0 port on the Pi4 have enough power for an SSD???
Along with the Argon40 case, I also bought a dedicated SSD holder that attaches via USB.
I also have the Argon PSU.....that appeared to be more powerful than the RPi version.
