Lost unallocated space

I was trying to move 30gb of free space from D: to C:, and while doing so it gave me an error. When back in windows, both disk management and acronis show C: as having the extra space, but windows does not recognize it, it still sees it as the old space without the 30gb, while the 30gb is gone from D:, so it's completely missing. Any ideas how to get it back without formatting, since this is my Windows partition?

here's an album with My Computer, Disk Management, and Acronis.

edit: maybe worth mentioning that this was movement across the same physical disk.
