I have a 3TB internal hard drive. It was an MBR initialized disk (which doesn't support hard drives over 2TB. You can however use a scheme to make the 3rd Terabyte its own partition. I did so by using Seagate's DiscWizard. I used the 3rd Terabyte for backups and I had a very recent one there. I refreshed my computer to factory conditions because the process said it would only affect its partition. However, now with a fresh operating system, I am only able to see the 2TB my OS sits in. My question is, has all the data on the 1 TB partition been lost or, if it is still there but hidden, can I recover it? Thank you for all your help. I am running Windows 7 64 bit

I'm confident TestDisk from CG Security will help you get your data easily.
It's free. Donload it from this page: http://www.cgsecurity.org/wiki/TestDisk_Download
After selecting the type of the disk (intel PC) then select analyze once it has finished you will be presented with the list of all found partitions including the actual and the lost ones. By selecting each one you may click on "p" to visualize its content and even copy it. If you did not find the partition you're looking for select "Deeper search".
Caution! If you select "write" the actual partition table of your HDD will be overwritten with selected partition scheme you chose in the results page. Obviously, this is suggested in case one need to revert its HDD to an earlier stage with everything back (Partitions and data) as if it was before.
