I installed a new 3gb HDD in my 2012 server.  When it was initialising I said do as MBR but then I can only use 2gb.

How can I get disk manager to re-initialize and ask me first question again?

Thanks Terry

First, delete all the partitions on the disk (destroying your data).

Then, once you have an empty disk, you can right click on left hand column where it says "Disk X Basic 3TB Online", and click "Convert to GPT". That will wipe out the partition table and set it up as  a GPT instead of MBR.

Did that, but it is still only 2gb.

do you really mean 3 & 2 are in GB?
Does Powershell have you tied up in knots?

from an administrative command prompt
list disk
sel disk x          // replace x with the # of the 3TB disk

Open in new window

Yes that got me to the first question again.  But even after I did clean, I then did list disk again and it still only showed 2tb.  then I did diskmgmt, GPT and still says only 2tb.
