New Secondary HD not allowing me to assign it a Volume Letter

Hello,

I am running windows 8.1, and I just put a secondary (actually 4th HD) Hard drive (Seagate Hybrid Drive ST2000DX001) into my computer. It shows up in the device manager, Bios, and disk management. Windows has not assigned a volume letter to it and all options are greyed out. It is listed as a GPT Protective Partition. I'm not sure if that's the issue. If it is, how do I fix it?

Thank You for your time.

Edit:
So I tried formatting the hard drive through the cmd and I get an error the request could not be performed because of an I/O error.
 
Where did this drive come from? I've seen that sort of issue arise on Mac-formatted drives. You might be able to use the diskpart command-line tool with the option "override" to get rid of that partition.

Open a command prompt as administrator and type "diskpart" to start it.
"list disk" to view a list of disks
"select disk X" to select the disk you want to work on (where X is the appropriate disk number)
"list partition"
"select partition Y"
"delete partition override"
"exit"
 


A new drive shouldn't be MBR or GPT out of the box; it ships blank. Also that I/O error makes me suspicious the OP got a second bad drive. That said, let's see if gparted succeeds where Windows failed. IF there's still a problem, RMA it (again)
 
If you can format it as a logical partition. If successful, you should be able to install an OS or use it for storage or whatever. I would keep a check on the drive and if you keep getting R/W errors or any other errors like failed to read sectors, etc---RMA the drive.

It loaded.

at /dev/sda - Gparted

It shows the hard drive 1.82TiB Unallocated
*sigh* Input/output error during the write on the drive.
Guess I'm RMAing it again.
 


OK then, is that the only drive attached? Unallocated is how a new (blank) HDD should appear. Right-click it, create a new partition and select NTFS as the format. Click the green check mark at the top row "Apply" to commit changes

well I don't really know what's going on, I tried again and it worked. rebooted and the pc sees the drive, first time clicking it it took a few seconds(10 maybe) to open the blank drive, then created a folder and pasted some files to see if it writes.

So, I received the replacements replacement. I'm still getting an I/O error. I originally had a SSD in the location. Would that prevent a different style HD from acting correctly if I had changed a setting to improve the SSDs performance? I have to believe that it's not the HD but my motherboard. Although the SSD that was there was working perfecting fine.

Edit: Reboot PC and it is formatting HD before assigning it a drive letter. I get Windows is Unable to complete the format. Check to make sure that the disk and drive are connected properly, make sure the disk is not read-only, try again.

So, I switche Sata 3 ports from 0 to 1, still got an I/O error. I then hooked it up to one of the Sata 2 ports and it works fine. I'm not really sure what the problem is. When I switch from 0 to 1 I moved the Boot Drive into 0 and it works fine. It booted quickly, no errors. So I assume the ports aren't bad, so what was the problem?

Edit: Well I hooked up my old SSD back up internally, and moved the new HD to a Sata 2 Spot. It reads everything fine. I'm curious now why the HD didn't like being in a Sata 3 location.
