Exfat recovery... please help!

#1 Post by tomtailford » 01 Apr 2016, 05:59

OK, so I've had a number of posts on here but still no resolution, apologies for a new post but thought I'd try and make things clear.

I have a GRAID 8TB striped raid in exfat which stopped working after I did something.

I managed to find files on the drive once but have since not been able to find the files again...

When I run testdisk:
Choose EFI GPT partition type (automatically found) - is this correct?
Analyse to show 2 partitions:
1 EFI System
2 Mac HFS (however it was EXFAT - I think I rewrote tables when I screwed with it)
Quick search says "check_FAT: Unusual media descriptor)

Anyone able to offer up any help on this?

Is this considered partition recovery or would I have more luck with some assistance in filesystem repair forum?
