I just bought a new drive the capacity is 12TB but the drive size shows 2.04TB. I am not sure if it's a hardware thing, I have a Dell Poweredge r410. Please help. // EDIT: It now is using GPT but still shows up as 2TB. //
You need to provide more technical information. Preferably CLI command output using CODE tags, with exact commands that you ran, the output you received - both successful and failures.
If you are unable to use CLI, you may be able to add sufficient amount of GUI snapshots here to provide more details about your challenge.
