Hey All,

 

I'm getting the above error on my cache drive. It's a 250GB SSD. Smart status shows everything as good, with no errors. The following is the device log upon boot:

Next time please post the diagnostics but based on the error best way forward is to backup cache data, re-format and restore data.
