Yes, it’s work ! 
Big thanks !
check_pdh “counter=\234(_Total)\1400″ ->
OK: \234(_Total)\1400 = 0
I found translation in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\CurrentLanguage
But I test this since 1 hour, and the counter is always at “0” …
Even when I “stress” the server’s disks with massiv data copy, and when the perfmon show that the counter is different from “0”…
One problem solved, but it’s not the end
Still investigating
