I have a 3TB hard drive. It used to be all available, but now only 2TB is "Allocated" and the remaining 1TB(Which is listed at 756.52gb) is "Unallocated". It appears in Disk Management, but i cannot edit or change it whatsoever, right clicking it just shows greyed out options. I have tried using E-US partion program but it did not solve it. Basically i just want that extra 1tb back into the primary C:\ where it used to be. I don't know what happened to change that.

Any help would be a godsend. Thanks.

It sounds as though you have a 3TB disk which is formatted MBR. MBR drives are unable to contain partitions larger than 2TB in size due to technological restrictions. To have a partition of larger than 3TB GPT is required. There are also partitioning requirements which dictate that for BIOS based systems the boot drive must be partitioned MBR. To find out more about partitioning requirements, GPT, MBR, and boot requirements for UEFI and BIOS systems, check out the section for Hard Drives and Partitions under the Windows Deployment Tools Technical Reference on TechNet.

Thanks for the reply. When trying that, nothing shows up in the Available slot and it says because the drive I am trying to extend contains boot files, it can't alter it.

It turns out i had 8gb of space unused on my hard drive. what I did was right click on the unused space and clicked delete partition on the unused 8gb then the extend volume worked for me. hope that helps.
