[SOLVED] Will reinstalling OS format my secondary drive?

Hello!

I have 2 drives in my computer and I want to reinstall my Windows. If I reinstall my Windows, will it also remove files from my other drive?
Do I have to disconnect my other drive for it not to get formatted?

tl;dr no

No, you can choose the drive (or even the partition) that you want to format when you reinstall windows. Just make sure that you only format the C drive, then the other drive will be totally fine.

Thanks!
