Any help would be great. I have 4 2TB drives set up in RAID 1+0. Disk Utility gave me a warning that the drive in Bay 4 was failing and when tested with Drive Genius it reported the same information. The drive was only a couple days old so Western Digital sent me a new one. I put the failed drive in an enclosure to erase everything on it and now it passes Drive Genius's Scan. Does anyone know what is up because. I really would hate Western Digital to charge me for the new drive.
