[smartmontools-support] SanDisk X110 -- Smartctl: Exception: json.cpp(121): Assertion failed: value

[Stefcho Piperov]

Hi,
I have a bunch of SanDisk X110 SSDs, and they all fail the
`smartctl -a` command. Other commands like `-s` `-o` and `-S` work 
fine. I can even schedule tests, but cannot see their results :)

This happens on the newest firmware for these drives (X232401), as 
well as on the stock firmware (X232201), so it's probably not related 
to a bug in the FW.

The failing command asksk me to contact this email, and provide the 
output of the `-V` command. See it at the end.

Hope this is helpful for improving the smartmontools!
- Stefan
