I installed windows 10. when initializing other ssd's i used MBR instead of GTP. and formatted them as ReFS because it was new thing i saw and was curios.

Format failed. i dont remember exact message but it said format failed and you have to restart disk management bla bla.

After that i cant format as ReFS. it doesnt even show up as option. i reinstalled windows and even cleared CMOS. it doesnt show up!

Now i went for NTFS and im okay with that but im really curios. I did clear CMOS and fully reinstalled windows. Why it doesnt show up? did i damaged my ssd's? or what can be the reason?

PS. the reason i cleared CMOS was because i was experimenting with new stuff. i enabled hot plug on sata ports. windows treated them as external drives, i disabled hot plug after that. maybe that has some affects, I also cleaned disk using diskpart to reinitialize ssds

Got it fixed by adding this key into registry. for some reason it wasnt there so i added it manually and formatted as ReFS successfully. (ref:http://mywindowshub.com/enable-disable-format-refs-file-system-windows-10/)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MiniNT

with following DWORD value set to 1,

AllowRefsFormatOverNonmirrorVolume
