Recovery of HFS partition

#1 Post by rtype909 » 04 Apr 2018, 17:03

How I got here

2tb drive, external, HFS single partition was formatted when i as attempting to write an image to a compact flash card via sudo dd command. the image was 300mb.

Drive no longer mounts and i have not attempted to initialize or write to it

Steps taken

I have recovered my files via Photorec.
I have tried testdisk ,to recover the partition via quick search to the raw (rdisk) device but with the details that appear I have attempted to write the correct partition map but it does not work, when checking with pdisk i get 'map is not big enough'

Anything else i can try

Is there way to locate an earlier partition map? or am i going about this entirely the wrong way?

When using TestDisk, use EFI GPT, not Apple partition table.
