what would happen if....?

[sam_roberts30]

what would happen if I took a 3tb drive straight out of a windows server and slapped it in an unraid as a parity drive without formatting or preclearing it? would it work as long as the drive is good?

 

I know I should preclear etc but I haven't got time and its a small pet project that will be taken down next weekend.

Yes, it would work fine (given your caveat "as long as the drive is good").    It will, of course, still have to do a parity sync (but that's true regardless).
