Hi all! I'm using a WD 6TB external drive to store my movies from my Imac..... I currently have it set to Raid 1 making it a 3TB drive. I'm wondering if I can repartition the drive back to Raid 0 without loosing data. If I can not.... does anybody know, would video quality degrade if I were to back up to another borrowed drive and put back on my repartitioned drive. Thanks!
