I just bought a new computer and wanted to put Windows 8.1 on it. After about 5 attempts of doing so, I accepted that that OS just wouldn't run on my hardware, for whatever reason. But in the process of installing, partitioning, deleting, formatting and doing whatever else to my HDD it now seems that about 750GB of space has become corrupted.

The 750GB of space is currently unallocated and it is completely locked, as far as I can see. I'm far from an expert on the matter, but it looks as though it's completely locked.

Here's a picture of the HDD in the Computer Management screen:

The model of HDD is the Seagate Desktop 3 TB, SATA 600, ST3000DM001.

During the final OS installation (Win7 Professional), before any partitioning there were two parts of unallocated space: both called "Disk 0; Unallocated Space", one of about 2250GB in size and the other 750GB.

All the normal options for Unallocated space (New Simple Volume, New Spanned Volume, etc.), except they're all grey-ed out.
