I've been replacing all my 4TB Drives with 10tb drives from WD Duos with no issues but today i took a 10tb drive out of a WD Mycloud EX2 Ultra and was about to replace a drive and i got this error:

Any help would be appreciated I guess i can force it but should i?

Edit : Clicked Storage > View Disks > DA1 > Wipe > Quick and that seems to have solved it
