I have a 2TB hard drive that I am trying to recover VHD files off of. The drive in question used to be formatted with the EXT4 file system, and was accidently formatted to LVM2.
I so far have made a backup image of the drive and done a scan of the disk with testdisk. Testdisk gave me a bunch of different partitions, most of which look like they are from the virtual hard drives. I have also looked at the hard drive with a hex viewer and most of the important data still seems to be intact.
How can I recover the EXT4 file system to salvage the data? I am a little lost on what to do now so any help would be appreciated.
