Hi [member=458]m654321[/member]

I faced a similar situation, mine was a usb 1TB hdd and it looked like I'd lost almost 800gb of data  :-X but I recovered my data/partition with testdisk following instructions from here: https://www.cgsecurity.org/wiki/TestDisk_Step_By_Step
Since then I  bookmarked it in case - hope never but better safe than sorry - I ever need it again. To be honest it was quite very easy and I recovered my data with little no effort.
Good luck recovering yours!

EDIT: By the way, I almost forgot but for best results you should use test disk from a live environment. Here: https://www.pcworld.com/article/3132067/...tdisk.html

Hope this helps!

Many thanks for your help.
I've now wiped the drive. I discovered I had a backup on setup3 below (Phew!!!!) , though the backup was done 3 months ago. So I only loose the last 3 months of data - putting it into perspective, the data represent a total of 15 years data: photos, videos, admin, etc, so I've got the bulk of it. I'll keep your & TC's links though, as they might be useful next time - though as you say let's hope there wont be a next time!
