[smartmontools-support] Raw output?

[Thorsten Wilms]

Hi!

How can I get the raw SMART values?

With new hardware setup in January, I have fs corruption requiring a
fsck run about every few weeks. smartctl showed me that health check is
fine, no errors logged, but the number of unsafe shutdown equals the
number of powercycles minus 1.

This is on Linux 5.8.0-53, Ubuntu Unity 20.10, with a Transcend 256GB
MTE110S SSD. I contacted Transcend support, who pointed me at their SSD
Scope software, but that’s Windows-only. They would like to see the raw
SMART output, though. I found examples that suggest `-a` should deliver
those, but what I get is:

```
~: sudo smartctl -a /dev/nvme0
