External hard drive turns off when not in use

Question

var fibo = function (x) {
  console.log(x);
  if (x === 1) return 1;
  if (x === 2) return 2;
  return fibo(x - 1) + fibo(x - 2);
};

// fibo = _.memoize(fibo);
var fibom = _.memoize(fibo);
console.log(fibom(5));

<script src="https://cdn.jsdelivr.net/lodash/4.17.2/lodash.min.js"></script>

Why does memoize work when assigned to the original function variable name (as shown in the commented-out code) but not when assigned to a new variable?

Solution 1

This feature is called by marketing "green" or "smart" or "Independent Power Management", and it puts the HDD to sleep when not in use. It can be removed using firmware tools from the manufacturer.

Solution 2

Have you looked at your Power Options within Windows to disable the drive spindown when idle after a certain amount of time?

Should be able to some how disable it under the Drive properties in my computer, possibly..

It depends on the drivers and OS... Better cut the feature from its root. :)

Some drives cannot be changed and will always power down.
