lorand checked Smart status and both drives are fine
I got a similar warning after I updated my laptop. It was a day from hell, and I don't remember the exact order of problems, or where among those problems the message appeared, but it was essentially the same. It warned that the SSD in the laptop had problems, but not yet reflected by SMART. But apparently potential problems.
I removed the Plasma SSD from the machine and replaced it with an earlier Budgie SSD that I'd replaced with the Plasma version. Since I suspected that Plasma SSD, when I again returned to Plasma on this laptop, I did a fresh install on an empty SSD (part of my day from hell) and spent most of the day installing software and configuring everything.
With the same warning appearing to others, I now suspect that there's nothing at all wrong with the suspect SSD, but it's now just a spare.
