All;

I have a Toshiba DT01ACA300 internal hard drive that I had loaded Win 7 when I built my PC. I had partitioned it to have a C and D drive. Win7 was on the C drive. I had accepted the Win10 upgrade and over several months and after a couple of crashes where I "lost" the start button, I decided to revert to Win7. I added a Samsung SSD as my boot drive (drive C) and loaded Win7 onto it and the machine boots fine and I have Win7 back as my OS. I then went into disk management and wanted to combine everything on the Toshiba drive to one large partition. I used DISKPART and did the CLEAN ALL command since I could not combine partitions in disk management. I then created a partition (named D) and all seemed well.

My Disk Management tool now tells me that I have this drive as Disk 1, it is a Basic disk, it is online and healthy. It has one primary partition and it is active, BUT it is only 746.52 GB NTFS. I can use this space just fine. I was certain this was a 3TB drive. What has happened to the rest of the space? I am at a loss as I thought I did everything correctly. What am I missing? Any help would be greatly appreciated. Thanks.

Solution
Most likely you'll have to install the latest Intel RST (Rapid Storage Technology) driver in your system. Check first with your motherboard's driver updates to see if there's a Intel RST driver available for your motherboard.

Also, ensure that you format the disk GPT (not MBR).

It's possible the IntelRST driver may have been an older version of that driver if the motherboard is an older one and the IntelRST driver had not been updated. If memory correctly serves me it was only beginning with the 10.1 version (but check this) that resolved the problem. Of course it's entirely possible there's another cause.

I had to download the setup utility from Intel and when I ran that it updated and a reboot and Viola!, I now have my extra space back. Many thanks for your time and patience in helping me.
