I am writing some software that maintains a large data space, and we need to be able to tag areas that have never been touched/written to, and be able to request those areas.

When we request areas we can add flags to the request for what we want, and currently the flag I am using for getting any hasn't-been-used-yet area is "virginal" - but eventually this software will be used by a larger audience, so I'd rather avoid the connotations that are connected with "virginal".

Also, I don't want to use a "negative" word like "untouched" because I think the double-negative can be confusing if you, for example, request a region where "untouched = false"

I feel like there is a word that I'm just missing that is both positive and doesn't have connotations involving sexual purity, but I can't think of what it is.

Suggestions?

CLARIFICATIONS:

1. I am clear that the word "unused" doesn't have sexual connotations. My problem with the word "unused" is that it's negative. Surprisingly the comments have shown that I wasn't clear on that.
2. I'm now realizing, thanks to some of the great suggestions, that the main issue here is that I have three states that I'm distinguishing between instead of two, which is why suggestions like "clean/dirty" don't quite work. I'm not just looking at the state of used vs unused. The three states are "allocated" and "free/non-allocated" and then also, "free and has never been allocated" - the last one I am trying to define.
