Yes I did. When I moved them over, I was hoping that the Disk Management function would show the partition and then unallocated space to make up the rest of the drive. But the management function would only see the limited area. When I deleted the partitions, it would only show the limited space as unallocated, not the full capacity. I am real close to throwing in the towel and just saying buy new drives, but without knowing the cause, the same issue could pop again.
