Windows may create two additional partitions during the installation process in addition to the main C: partition.

The first partition is the recovery partition and is around 300MB in size. This is a separate, self contained Windows installation which contains a minimal feature set of debugging, diagnostic, and repair tools. If Windows becomes unbootable, the boot loader can boot into this installation to aid in recovery.

The second partition is only created when Windows is installed on a computer with UEFI firmware and the UEFI boot process enabled. This creates a 100MB EFI system partition that contains the Windows boot loader programs.

HI

If drive letter d: exists then it probably can be viewed using windows explorer

If you can find disk management ( via control panel or Google) you can see if d: is located on SSD or hard drive

Without a lot more info it is difficult to say more
Is this a laptop or desktop
What make & model ?
Did it come with ssd ? Or did you fit it

Many PCs have hidden recovery partitions


Toshiba windows 7 laptops often put recovery files in folder on second partition which is visible and has drive letter d:

You get prompt to make recovery DVD set until you turn this prompt off or make set of DVDs
