HDD not recognized in Disk Management

[GABRIELC97]

Hi all, 

I just connected a hard drive to my build. I noticed it wasn't recognized in disk management, but it did appear as a device under device manager. I can't figure out how to assign it a letter and use it. I've tried updating drivers and removing and reinstalling the disk with no luck. Any ideas? 

Thanks in advance.

I have had this happen with usb flash drives before after using them to install linux and such. Note the size of the drives currently installed as well as the new one. Do the following:

 

Open a command prompt (cmd.exe) as administrator
run the following commands:
C:\> Diskpart
DISKPART> list disk
DISKPART> select disk ? (replace ? with disk # that matches the size of the new one. Make sure you select the correct disk. The disk # is usually the highest one.)
DISKPART> clean
DISKPART> convert mbr (or gpt) (use gpt for disk greater than 2TB)
DISKPART> create partition primary
DISKPART> select part 1
DISKPART> format fs=ntfs label=(name of disk if you want one) quick
DISKPART> assign letter (letter) (use a letter not currently in use)
DISKPART> list volume (should see the disk listed, and it should show in disk management and Explorer)
 

Just take your time and follow every step. Windows may prompt you to format the disk part way through the steps, just select not to and complete the steps with Diskpart.
