I started to merge an empty 200GB partition with a 500GB partition and canceled the operation about 10 minutes into it. (ya that was dumb) the 500GB then showed unallocated and I couldn't see any files on it. I used data recovery software to get all the data off but it is all corrupt. its all video and image files. no matter what I try to open any of the files with I get "cannot determine file type" error. windows is showing all the file types properly and attempts to open them in the proper program. a few of the video files will kind of work with no sound or scrambled picture etc. I was able to use Partition Manager to reallocate my partition without reformatting it. When I rebooted, windows did a check disk for integrity on both partitions and ran through every file. The files are all back but they are corrupted the same as the ones I recovered using the data recovery software. any help fixing my data would be much appreciated!
