Hard Drives Do Not Show Properly In Disc Utility
Hey,
Ok so I need some help. Here is the story. I have four, 3TB Hitachi HDS723030ALA640 Media hard drives and all of them work fine. However, last night I took two of them out and placed them inside an OWC Mercury Elite enclosure because I was going to use them as an external backup. long story short, the enclosure can only read up to 1.5TB drives, so it was not a good solution. I took the drives out of the enclosure and put them back in my Mac. This is where the problem occured. The drives both work, meaning I can save data to them. However, there are no options to RAID them, erase them and Disc Utility no longer displays them like the others, I'm very limited on options with these 2 drives and can only see the First Aid and Partition tabs.
PROBLEM 1: Disc Utility no longer displays the names correctly, which should be 3 TB Hitachi HDS723030ALA640 Media like the others. See this screenshot: http://d.pr/i/MVQ3 . The two drives with the issues are the top two, TM and Untitled. And I have no way of renaming them, I can only rename the second item under the top level.
PROBLEM 2: The only tabs available are "First Aid" and "Partition", and the Partition tab does not allow you to select anything. The Erase, RAID, Restore tabs are all gone.
PROBLEM 3: I noticed that these discs do not show any type of description or SATA connection or which bay they are in. For exampel, this screenshot shows one of the drives that is working correctly, http://d.pr/i/Wdy0 . This screenshot shows one of the problem drives, nortice the info at the bottom http://d.pr/i/lNn

I've tried everything I know. Both drives verify fine and repair without issue, no problems are found. I also tried to boot in recoverty mode and use disc utiltiy there and I get the same options.
I've tried to manually erase the disc with terminal using this command below, but it tells me "A volume was specified instead of a whole disk: disk3s2. Specify a whole disk, or instead use diskutil eraseVolume to erase a volume on a specific partition"
Here is the terminal command I used:
diskutil eraseDisk JHFS+ 3TB Hitachi HDS723030ALA640 Media disk3s2
How do i fix this? Any help is appreciated.
