A non-negative synonym for "unused" or "untouched" that doesn't have the sexual implications of "virginal"

Question

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.

Answer 2

I think you could use raw to describe areas and data:

Raw information has been collected but has not yet been studied in detail: raw data/evidence/figures (Cambridge)

not being in polished, finished, or processed form (M-W)

I see on computing sites that it is used for areas and locations.

Answer 3

Good question!! In my experience in IT, we would often use the term “empty” to describe unused disk or data space with our clients in other departments.

Here is how “empty” has been used on Quora:

“… when a file is deleted or put in the recycle bin, [the file] is not deleted, but instead, the disk space is marked as empty …”

Sure, you’re not talking about file deletions as in that quote, but might “empty” work for your purpose? Best of luck with your project!

Answer 4

For the three states you describe why not in use, used and clean?
