I think that D: partition was created manually, and the recovery one Windows creates itself upon installation by chipping off the free space at the end of its main partition. In fact, if your Windows installation has lives long enough, you might even end up with several 😂
I kid you not, some update made the recovery system no longer fit into the old partition, and Windows was chipping away some free space again to create a new one.
