That didn't work for me, the command is not recognised by diskpart.All you need to do is rewrite the Index/System Volume and it will be as if it never happened.
Or try this with Option #1 (CMD): https://www.anyrecover.com/external...x-raw-external-hard-drive-without-formatting/
I found this after scanning for 3 days to try rebuild the partition. Data recovery is working well enough, it's just about finding somewhere to put it now hah. One problem after anotherthis happened to me before.
rebuilding the file index was useless through diskpart.
i used a software to retrieve 90% of the data. most recovery software you can download as demo or time trial. see which one works for you.
