Demolished the partition, is it possible to recover the data?

Question

linux

Ubuntu OS, used ext4, ssd drive. Fdisk deleted the partition, selected g create a new empty GPT partition table, before that the partition was marked as disklabel type: dos. What could be the algorithm of actions? or data "everything"?

Answer 1

0) make a sector-by-sector copy of the disk
1) try the trite TestDisk. If nothing else has been written to the disk, restoring the partition table is not as difficult as FS.

Answer 2

You can restore if you have not yet written anything to this partition and have not created a new file system. If possible, it's better to make a disk image via dd, booting from a LiveCD. KO hints that you need to write the disk image to another device, not to the SSD itself :).
Next, you will need to find the place where your old ext4 started from. If it is not overwritten, it can be mounted using the offset option.
Here is a case very similar to yours, roughly telling how to do what:

Answer 3

Try gpart to look for old partitions - www.tldp.org/HOWTO/Partition/recovering.html
Well, this is provided that you did not create new ones.
