Compdoc: Your spinrite comments just show how dangerous some knowledge is without propper understanding. Spinrite does indeed force SSDs to "fix" themselves because it reads extensively (causes heat) and forces "half" working areas to be marked bad. Most SSDs has minor defects from day one. Just like most spinning drives has bad sectors marked when it arrives from the factory. You can force the same result by reading all parts of a SSD drive extensively. Spinrite does not per definition fix a SSD drive, but it does make the firmware (software) in the drive detect read errors that might not be relocated during normal operation. I have forced SSDs to fix themselves since i got my first SSD more then 10 years ago. Often with the help of Spinrite.
