SSD reset without loosing data on HDD

[LGJ gaming]

I have a very high spec pc and the OS is stored on an SSD that is running at 100% usage. How do I factory reset SSD without factory resetting my HDD

If your HDD is just data or a STEAM folder, no problem with a secure erase and clean install on the SSD. Any games or programs that reside on the HDD will have to be reinstalled so that the OS registry has proper data. One way around that would be to buy a bigger SSD and clone the old SSD to the new one, then use the old one on another machine or as a scratch disk.
