When i installed the hp microserver i used the original 250gb hard disk as primary disk where i installed the dsm. When i was sure everything was working good i ordered 3 x3tb wd red to make my raid 5 volume, so now i have 2 volume, simple volume and raid 5 volume, i want to change the 250gb disk with a spare 2 tb disk i have ( i use primary disk as destination disk for download station). If i remove the 250gb i have to reinstall everything?
