Today I spoke with a customer who had a RAID enclosure with 2 drives in it with a virtual size of 6TB or actual size 3TB. One of the drives in this enclosure had gone bad. He decided to purchase a new drive and had the drive duplicated automatically by the RAID. This RAID was attached to his MacPro with a 1.5TB of data. He then realized that the enclosure was going to duplicate the data but also the 2nd drive was failing too. At this point he purchased another drive to install and recreate the RAID. He contacted us to recover his important data on these drives.
