Monitoring temperature and HDD status?

Question

Hard disks

Advise something sane for monitoring hdd. First of all, monitoring the temperature of hdd is of interest.
I tried several options, including the vaunted hddlife - out of three WD hard drives, the program recognized only one ... etc.

Answer 1

smartctl or hddtemp

Answer 2

I also did not understand the full depth of the depths, but I will answer a specific question from the comments of the topic:

var a = [1,6,8,10], b = [7,8,9,10,12];
function _intersection (a,b) {
  return a.filter(function(obj) { return b.indexOf(obj) >= 0; });
  
}
console.log(_intersection (a,b));
