Formatting disk in OpenWrt - problem

[MusiCManiaC]

I bought a second disk for my x20pro , unfortunately zidoo doesn't recognize him. I tried to format it myself in OpenWrtbut I did not succeed.Is the problem in the partition? See two screams and I will be grateful for help in formatting.Is OpenWrt the only way to format?There are a lot of functions that I don't understand

Subject to close, I solved the problem using win 10.

That would have been my solution also. Much easier to format the drive using a PC.
