While making a connection to mongod, set safe to true, for instance here is how it can be done using python driver (pymongo)

from pymongo import Connection
connection = Connection('localhost', 27017, safe = True)

By doing so you will get write acknowledgements, else it would be simple fire and forget.

MongoDB by default (in some drivers) does not enforce a safe mode whereby the database will physically respond to every call you make to say whether or not it was successful.

However in most drivers there is a getLastError() and you can, of course, enforce safe mode on calls using something similar to:

update({},{},{safe:true});

Using both of these methods will allow you to return problems MongoDB might get in handling your operations.
