This selectivity is by design. Operating system developers assume a user might have multiple storage devices for different purposes: one drive for the OS and programs for speed, another for bulk media storage (photos, videos, games), and perhaps an external drive for backups. A clean install is intended to provide a fresh software environment, not to act as a data-wiping tool. For example, a PC owner with a 500GB SSD (drive 0) for Windows and a 2TB HDD (drive 1) for games and documents can perform a clean install on the SSD without affecting a single game save on the HDD. After the reinstall, the OS will recognize the second drive as a separate volume, fully intact.
