[smartmontools-support] SSD bug ?

[A. Kapetanovic]

Hi,

The SSD on my laptop seams to have problems (loss of data) ; so I am trying  to look about with smartctl but can't believe the results : all what I did :

smartctl -t short /dev/nvme0n1p5
smartctl -t long /dev/nvme0n1p5
smartctl -x /dev/nvme0n1p5

Has instantaneous results. I don't understand, did I a mistake ?

Regards,

aka
