STOHDTO (Six To One, Half-a-Dozen To the Other). In a technical manual, there may be a clear distinction between these terms, however in the English language these words are synonymous. In fact, Dictionary.Com uses the term "state" in the very definition of status (see #2), and vice versa (see #3).
The difference is really open to interpretation. Mine is below.
In my opinion, a status is one of a pre-defined set of conditions, for example, not ready, in progress, almost ready, and ready to use (see http://docs.webplatform.org/wiki/Property:State; ironically, WebPlatform.Org calls these "states", but I think they are more like "statuses"). I believe statuses should be arranged on a spectrum, and an object usually moves from one end of the spectrum to another, having exactly one status assigned.
States, on the other hand, are conditions that don't need to be arranged in any sort of order or on any spectrum. An object might possibly not have a state assigned. (Although I don't think it's possible to assign multiple states to an object. Usually people will refer to "the" state of [blank], not a state.)
More from Dictionary.com (emphasis mine):
State, condition, situation, status are terms for existing circumstances or surroundings. State is the general word, often with no concrete implications or material relationships: "the present state of affairs." Condition carries an implication of a relationship to causes and circumstances: "The conditions made flying impossible." Situation suggests an arrangement of circumstances, related to one another and to the character of a person: "He was master of the situation." Status carries official or legal implications; it suggests a complete picture of interrelated circumstances as having to do with rank, position, standing, a stage reached in progress, etc.: "The status of negotiations."
