do these diagnostics tell me my MMC card is toast?

I had a flash drive that I thought was toast, it gave intermittent
errors when I tried to write to it which got progressively worse until
one day I just couldn't write to it anymore. I let it collect dust for
a week then decided on whim to format the thing and its been working
fine ever since. No problems since, I never did figure out why it
happened. In hindsight the only thing I can think of is maybe  that
week there was a kernel update that fixed a bug or it might have been
that I swapped it between nix and doze boxes a lot. Don't do that
anymore but its all supposition since I don't have any facts. This as
you may have guessed is just my long winded way of saying format it
for giggles and see what happens.
