It's useless to search partitions inside a partition.
Select the PhysicalDrive containing the partition H:, go in the Advanced menu, select the partition, choose Boot, RebuildBS, List.
If you can see your files, choose Write, confirm, Quit and restart your computer.
If it doesn't work, use PhotoRec.
