Re: Intel RST driver -> SSD bug ?

Do you own the four books I previously recommended?
I wrote their names on a postit, for the moment. I will begin by looking on
Test::Most
Thanks lot for these information.
Have you considered hiring a tutor or consultant?
I want absolutely do this script myself.
Please condense your script down to a short example that demonstrates
the bug, post your code, explain what you expect the code to do, post a
sample run, explain what happened, and explain why what happened does
not match your expectations.
I have found the reason of sometimes :
amel@laptopasus:~/fp/test.algoB$ ./algo-B1.pl
2020-01-01 - 2020-08-31
And sometimes :
amel@laptopasus:~/fp/test.algoB$ ./algo-B1.pl
Undefined subroutine &main::lisblocage called at ./algo-B1.pl line 161.
Is is simply the effect of the mixture of :
1. The keys of a hash given by keys() function come in different order (in
different executions of a program).
2. I did a mistake : 'last' but should be 'next' in the loop on the keys
above.
But the questions of the SSD is always here, I really would like a "true"
diagnostic.
I did
smartctl -x
But the result is instantaneous :
# smartctl -x /dev/nvme0n1p5
