How to remove GNU/Linux from 2nd SSD?

When i need that storage i will delete it. But how can i make it NTFS?

you don’t give any context or reason in you post, but NTFS is a Microsoft format and while some distos can use it, mostly, Linux avoids it.

if you’re installing Linux - I’d suggest you want to avoid it too.

but I’ll also suggest that you want to read this - which may help you get the most out if this forum, because many of your posts lack the details we’d require to be more than “generic”. if you add context and technical back ground, you nay get more focused replies.
