Currently i have created a new flat file with the exact 250 GB and placed it into the delta chain. I was able to boot with a live linux iso and currently a sh*t ton of unattached inodes are processed by fsk and i assume tons of files are going to be dumped into the lost and found folder. Ah, yes - prior testdisk tool from GPartes Live iso repaired the partition table and other stuff.
Since i run here with an empty / blank flat file and the deltas, i expect to miss a lot of files.
I wonder if i should run the same procedurte with that "rescued" 21 GB truncated flat file. Not sure if i can do something like linux dd to copy the content of my 21 GB file into/over that newly created 250 Gb flat file. Would that work?
