It is a Crucial 128GB one.
Cockpit is showing me an error of /sys/firmware/efi/efivars 0 free

Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

The above only provides legacy SMART information - try 'smartctl
======== END OF SMARTCTL ====

Is it time to say good by and replace this disk? Should I get a larger one? It has the boot info and operating system.

Thanks for your insights
