I do not know what to look for in preclear reports. I havent had to upgrade my server much but I am maxed out in storage and need to add some 8tb Seagate drives. I need my server back up asap since it is the media source for our home. I finished running 1 preclear on two 8 tb drives and I want to start building my new case now and get the server back up. I am copying the preclears and also wondering if running only 1 preclear is sufficient?
