I made a major mistake and used Paragon's Partition Manager to attempt to resize the partition that contained ~400GBs of video files. I wanted to add space from partitions that I had removed located before the video partition. It increased the size of the partition exactly as instructed, but it appears to have erased the contents and left the partition marked as free space.
I have O&O's UnErase, but haven't used it before. Since it didn't see the free space, I used Disk Management to make a partition out of it, but did not format it, because I thought that would make recovery more difficult. UnErase now sees the partition, but complains that there is no file system, and doesn't appear as though it will work unless I do format it.
I'm wondering if there is some recovery program that wouldn't require the partition to be formatted to work?
