I accidentaly formatted my external hard disk while creating a bootable startup drive using "Startup Disk Creator" in Kubuntu 14.04.
So my single 2TB etx4 partition vanished, to be replaced with a 2TB FAT32 partition.
I haven't used the drive so the data should still be there.
I tried the standard procedure with testdisk:
Selected disk --> Partition table type: Intel --> Quick Search --> Deeper search
but it found only the new FAT32 partition, plus some random HFS and FAT partitions that I believe are ISOs and virtual machine drives that were on the external hd.
I tried again the same procedure selecting:
Partition table type: None
In this case it actually found more partitions including and ext4 partition as big as the drive is, that I believe could be the one I lost.
When the search finished I tried to see the files on the partition using 'p', but to no avail.
At this point I think I pressed 'q' one time too much and returned to the main menù losing my Deeper scan data...
This is the log of the deeper scan: http://pastebin.com/rhFg1yqF
This, taken from the scan log, gave me the idea that something could be done, but I don't know what and how at this point.
Code: Select all

I thought that recovering a simple format of an ext4 partition should have been possible.
Am I doing something wrong? Should I give up the idea of recovering the partition?
