new disk setup

I am doing a fresh install of gentoo or I might do Debian but this isn't a comparison question. I'm trying to do the cleanest and most fresh installation and I'm wondering if my disk is "fresh and clean or blank" if I create a new disk label and partition table using fdisk. I know that nothing is done to erase data, so is it really fresh? I don't want to have to wait to write 0s over my hard drive using dd; it takes too long, but I will if it is the only way to have my drive fresh.

When the partition table is erased and rewritten, information about any previous partitions is lost. When you create new partitions and format them, the new file system will contain no references to any data that may have existed on the drive previously.

While the old data is technically still there as the sectors haven't been physically erased, it will be silently overwritten when new files are created, and can in no way interfere with your new installation.
