It's a 480 GB SSD, I don't think Spinrite will help

The box is a fairly recent reload, I'm not keen on doing it again. I was hoping someone might have a magic bullet.

Actually, I read recently that spinrite level 1 is read only, and can work wonders on SSDs.

I'm not even sure how that would make sense?

You can read from SSDs almost indefinitely without causing wear. It's the writing that causes problems.

So by doing a level 1 read across the drive, you're forcing the wear logic to realize failing sectors are having problems, which it then swaps out to a spare one.

And all of our listeners
just got a new tip for running SpinRite, if you have a drive which, like this - the problem
is that all of the other levels are writing something. Level 1 is a read-only pass. And
that's why it's safe to run on thumb drives, because it doesn't write anything, absolutely
nothing. It only reads.
But the beauty of that is that, as we were saying before, the act of reading shows the
drive it has a problem. And clearly this, whatever was going wacky with this and a couple
other drives that Mike found, writing gave the drive fits, but reading was okay. So
reading was sort of eased into it more gently and allowed the drive to fix the problems so
that then writing to them was writing to different areas because the bad spots had been
relocated to good areas on the drive. So that's a great tip. It'll definitely make it into our
notes for the future.
