Hotfix KB2731284 or later update is installed, no need to zero-out data files?

Question

I have run mongorestore thousands of times and now of a sudden I get "Hotfix KB2731284 or later update is installed, no need to zero-out data files"

What on earth does it mean and what do I do about it?

Answer 1

It has something to do with this bug.

On Windows platforms code was previously added to zero-fill each newly allocated data file in order to work around an issue described in this Windows Knowledge Base article.

Take a look at this thread, which looks like has an answer. I can not test it because I do not have windows.

Answer 2

Have you installed Mongodb lately? if so you need to create a folder in this address:

C:\data\db

This is the default address you can change it.
