    Only 1/2 of my hard drive is available


    I upgraded my gaming PC's hardware and software. I add (2) 500GB disks from a system I wasn't using anymore.
    One disk was a Windows10 x32 system disk and had 4 partitions , one partition was 'Reserved'. I deleted all the partitions but when I was done I only show 298GBs instead of 465.75 like all 3 of my 500GB drives.

    I used diskpart and tried clean.
    Windows -10 Pro x64
    Version 10.0.19042 Build 19042

    The first upload is from Disk Manager and the second is from Macrium Reflect which shows the true state of the disk.
    One article I read said to initialize the disk with GPT but it still shows only 1/2.

    Any ideas?
    Thanks!!

    Are these SSDs or Spinners? Does the problem disk show all the capacity if replaced in the original system?

    298 GB is the exact size a 320GB disk would show. Are you SURE it is a 500GB disk? 320GB is a fairly common disk size.


    Open a command prompt as admin and run these 3 commands please. Post a screenshot of the results


    Diskpart
    list disk
    list volume



    /edit

    Yep that`s a 320GB drive.

    Your System has 3 500GB drives and 1 320GB drive

    Macrium is still not showing the 320 drive correctly, unless that snip was taken before you formatted it. It looks fine in Disk Management.

    Man _ I am sorry - I feel like an idiot!!
    Partition Disk #3, Partition #0
    Model WDC WD3200AAKS-00L9A0 ATA Device it is a 320GB.

    When I looked at 'System Info' I got confused. I thought it was (Model ST500DM002-1BD142 ATA Device) a 500GB device.

    I apologize and thank you for your help!

    No need to apologize. We've all been there at one time or another,
