Hard Disk Failure

[johnnoe]

Is it possible to detect the hard disk failure using the event manager. Can anyone share some idea about detecting hard disk not connected or not recording events?

Bit more info might help. Model numbers, symptoms etc.

Dahua NVRs do a S.M.A.R.T. check - is that failing?

Thank you for your response.
I am sorry about the vague question.

Actually my NVR showing the alert correctly, when I unplug the HDD it shows 'No HDD' message.
I need to get all the events using an API. I see that it is possible by using the url ip/cgi-bin/eventManager.cgi?action=attach&codes=[AlarmLocal etc...].
In this I am not able to get the HDD failure alerts. I am able to see it in the log which can be fetched using the url action=startFind&condition.StartTime=2017-5-10 12:00:00&condition.EndTime=2017-5-10 15:00:00 and doFind.

I am not able to get the HDD alerts using the eventManager API, is it possible? Or do I need to use any other API like log.cgi to get the same ?
