I recently purchased a WD World Book II, a 2 TB one. I call it the "White Box". It has those 2 1TB drives, and they were in this RAID 1 config, only giving me about 1 TB. I could not delete the raid array, and I took the drives in a Linux box. But I also deleted the entire partitions of the disks, and I cannot even et the existing RAID array on this WD White Box. The drives are fine, but I cannot get them to work on the WD White Box.
My goal was to get back to a real 2 TB storage space. If I cannot get those drives back in the White Box, I can re-use them elsewhere, but this would mean a waste of the firmware and network connection. After the fact, I read that, anyway, the network performance is rather poor.
