Windows 8 Upgrade, Partition Unallocated

    Question

  • I have a Seagate 3TB Barracuda XT drive on my Asus P6X58D Premium based system using the Marvell 9123 Sata 3 storage controller.  Running Win 7 Pro x64 I had it divided into a a 2TB partition (Basic) as my C volume and a 1TB partition (Basic) as a spare volume.  Afterer upgrading to Win 8 Pro x64, the 1TB partition is grayed out and marked as "Unallocated".  Disk Management can do nothing more than display "Properties" on this volume, and neither Paragon nor Easus (spelling?) can manipulate this 1TB volume at all. I've been searching the web for more info or others experiencing this issue and have not been successful.  Anyone else encountered this?  I'm stumped.

  • Try using the ASUS Disk Unlocker software.

  • Thanks Carey for responding.

    Unlocker is supposed to be compatible with my chip set, but it fails to install, I've tried several times.  I get the following message:

  • Carey,

         Found a newer version of Unlocker, 2.12, in another location that supports Windows 8.  It installed fine.  It's extremely basic, the two options were to recover a virtual disk or create one.  I selected "Create", so it set up the unallocated space from the 3TB drive as a new drive 3 (see image below).  I'm a little unclear as to what actually has occurred in doing this, but it's working fine.  I'll be researching more to better understand what was set up.
