First off - if you have any "critical" files on the SSD, back them up to another device. (Assuming you don't have a current or recent backup)
The SSD itself might have taken a one-time hit or it could be a warning that it is or will be "Not long for this world". Then you can perform whatever testing you need to satisfy yourself that the SSD is still usable or not.

SSD Drive should support S.M.A.R.T
https://en.wikipedia.org/wiki/S.M.A.R.T.
In Raspbian you can install Smart Monitoring Software:
Code: Select all
sudo apt-get update
sudo apt-get install gsmartcontrol

An SSD will normally map out back blocks on its own, until there is no more reserve space to do it, at which point the drive is dying. Check the manufacturer's website for diagnostic tools. Often they will have software to test the drive and report its condition.
