Mac disk utility problem - data missing

Never thought I would be posting a question along these lines, but here we go.
So I had an external hard disk with two partitions. One NTFS and one HFS+. The NTFS partition was empty. I wanted to use the NTFS partition with Time Machine so I used Disk Utility to reformat it HFS+.
When the format had completed, yes, the NTFS partition was now HFS+ BUT
the other partition had disappeared. When I looked at it in disk utility it had a name like "disk32s".

It wasn't mounted and when I clicked 'mount' the Disk Utility view flashed/refreshed but nothing happened.
So it looks like somehow the partition map got wiped in the process. Great.
Disk Utility's own "repair" function won't run on it. I've tried DiskWarrior but a) when it starts it says it's inspecting the disk in a 'final' attempt at rescue, and b) only runs for an hour or so before crashing. I own a copy of SpinRite but haven't yet run that on it.
I *have* made a "backup" of the - what appears to be but I hope is not nothing.
So any tips on what applications to run on this drive? Ideally I would like filenames and tree structure intact as the contents were photos which will be a pain to sort through as the EXIF isn't reliable with the older ones for sorting purposes.
THANKS SO MUCH
