Hi all. By a mistake, I accidently deleted a wrong NTFS partition and then created a new ext4-partition on HD. How can I “undo” this action or is old data already doomed?
It really depends on how much damage the ext4 format did to begin with. If all ext4 does is write a superblock, then your data is probably all there. Problem is there’s no entry point into the NTFS format cmd that I know of that says “just write superblock info and don’t touch anything else”. So what you have to do is cheat.
- create a DD image of your hard disk and save it somewhere safe. You’ll probably need a extra disk to do this because of the sheer space being used.
- format the disk as NTFS
- compare the two disks at the block level, the image you made vs the actual disk using the
cmp
utility.
