First, delete all the partitions on the disk (destroying your data).<br />
<br />
Then, once you have an empty disk, you can right click on left hand column where it says &quot;Disk X Basic 3TB Online&quot;, and click &quot;Convert to GPT&quot;. That will wipe out the partition table and set it up as &nbsp;a GPT instead of MBR.

Hi<br />
<br />
Yes that got me to the first question again. &nbsp;But even after I did clean, I then did list disk again and it still only showed 2tb. &nbsp;then I did diskmgmt, GPT and still says only 2tb.

Hi<br />
<br />
I installed a new 3gb HDD in my 2012 server. &nbsp;When it was initialising I said do as MBR but then I can only use 2gb.<br />
<br />
How can I get disk manager to re-initialize and ask me first question again?<br />

Thanks Terry
