There are some little things to watch!
Exfat appears as a NTFS-partition but the file system is formatted as exfat.
TestDisk will only display a NTFS-partition and running on GPT as MS Data.
You should mark each MS Data partition and check the bottom of the display.
Example:
It's an NTFS partition ( because it's Intel MBR and not GPT, under GPT it's MS Data).
At the bootom of the screen you can watch it as an exfat-boot sector.
It's a tip to locate exfat better!

Re: Wrote the partition table thinking I'd fix it...
I don't understand your reply (sorry!)
The disc used is a GRAID - which was formatted using a MacBook Pro and is exfat.
So I selected Intel/PC Partition (although it detected EFI GPT) and now I get this:
Is this good news?? Here's the log - any advice what to do next? THANKS FIONA!

Re: Wrote the partition table thinking I'd fix it...
Sry that you didn't understand it!
Will make an effort to guide you through.
On your picture, the second partition ist exFAT.
Did you select it and were you pressing p to have a try to list your files?
You should select this partition:
HPFS - NTFS 25 159 7 972792 89 33 15627497472
You can watch it here:
Info will follow.

Re: Wrote the partition table thinking I'd fix it...
Now it won't show that partition any more... from a quickscan I got:
Another thing you might want to know... when a mac formats an exfat drive it says this in windows:
Attempting to list files on this partition does this: There is no option for list files on other partition.
Confused!

I did create a backup (I think) and am able to load this - would you do this?

Re: Wrote the partition table thinking I'd fix it...
So you know... this is what originally happened:
RAID 8TB (2x4TB striped raid) - EXFAT - showing up as RAW in windows / not showing partition in mac (only device)
Testdisk detects EFI GPT partition
Analysed - showed correct partition name (Chimp)
List files - showed all my files
Backup - saved current pariton list (not sure where I can find this on my MacBookPro?)
Wrote partition structure to disk (thinking it would fix)
List files - "support for this filesystem hasn't been implemented"
Says MacHFS? (Confusing as 99% sure it was exfat)
Backup - saved current partition list as follows:
Please tell me I've not royally screwed myself :/

Re: Wrote the partition table thinking I'd fix it...
Sorry, any ideas on this - have I crashed my raid?
Will I be able to recover? The files were visible before I wrote my partition table

Re: Wrote the partition table thinking I'd fix it...
Any ideas on this please?
Sorry to bring up this old post but I've still got this drive sitting in my drawer and hoping for it to be recovered.
Is there any other ways of recovering this data?
