Your SSD is warning you: what a S.M.A.R.T. error really means

If Windows or your PC's firmware shows a S.M.A.R.T. failure predicted warning, your drive is trying to tell you something important: it may be on its way out. S.M.A.R.T. is the self-monitoring system built into every modern drive, and a failure prediction usually means worn-out memory cells, too many bad blocks, uncorrectable errors, or a dwindling pool of spare capacity.

Do this immediately: back up everything you care about to another drive or the cloud, starting with the files you can't replace. A predicted failure can become a total failure with little further warning.

What you should never do: don't run "repair" or "optimize" tools on a failing drive, and don't reformat it hoping the warning goes away. Those actions stress the drive and can turn a recoverable situation into permanent data loss. If the data is critical and you can't copy it off, stop and consider a professional recovery service.

The good news is that a S.M.A.R.T. warning turns a catastrophe into a planned, cheap drive swap — if you notice it. Windows 11 now surfaces drive health under Settings > Storage > Disks & volumes, and Tendvane's Disks tab reads the same S.M.A.R.T. status for every drive in one place, so you get the heads-up before, not after, the drive dies.
