I suspect this is the crux of the problem. the adapter I connected is a card reader. You put the SSD in a little plastic jacket that holds the SSD in such a way that the card reader can access the edge connector but the holder jacket has no electronics.
SD, *not* SSD; two different things. SD cards are notoriously unreliable, and it sounds like it went bad. That happens, a lot. Throw it away, get another one. (There are less-unreliable cards, but they are more like $100 than $5 and rarely seen at consumer retail locations because typical consumers won't pay that much.)
