    Win 7 Pro 64-Bit is unable to see my 3TB hard drive partitions

    mtl777

      I have a 3TB hard drive on which I created three logical partitions and no primary partition at all. This was done in Windows XP. I am able to see the partitions in Windows XP and access them perfectly. But when I mount the drive on a Windows 7 Pro 64-Bit system that I recently created, Windows 7 is unable to see the partitions.  My drive is seen as unallocated space of only 746.5GB in Disk Management.

       

      I came upon this suggested solution:

       

      https://www.partitionwizard.com/partitionmanager/3tb-drive-shows-746gb.html

       

      The solution suggested for Intel systems is to install the latest Intel® Rapid Storage Technology driver.  For AMD systems, they recommend to update to the latest chipset and SATA/RAID drivers.  Since my system is AMD (Phenom II X3), I would like to know where to find the latest chipset and SATA/RAID drivers for my mobo, which is an old Asrock M3A790GXH/128M.  It has an AMD 790GX chipset for the North Bridge and AMD SB750 chipset for the South Bridge.

       

      Could anyone please help me find the latest chipset and SATA/RAID drivers for my system?

       

      Thanks in advance for your much appreciated help!
