basically it's a real good idea, to give that kind of information in a log file. But on the other side a warning should be a hint for an acute 'dangerous' system-status (which could potentially cause a damage). When I recognize a warning, it is the urgent call for me to act and to solve the problem (in order to avoid futher problems).
But in this case there isn't a real problem at all (except the possibility, that the SPTD-driver can slow down I/O of my drive).
Therefore I think it would be better, to use another icon for this kind of information - maybe a blue orb with a white 'i' within, to show, that the log-entry is for informational purpose (nevertheless the log-entry could help to solve problems, but it wouldn't be so irritating at all).
Greetings an thanks for your efforts
