Revert repair operation

[adrienafl]

Hi !

I'm looking for an easy way to revert the repair process. I ran it on an exFat partition by mistake. All the data is still accessible (I ran an fsck_exfat then I tried to mount the disk manually on debian and all data were there). The issue is on OSX : the system sees the partition as HFS+ instead of exFat because of the script.

Any help to revert the operation would help. I can't play with this disk and I don't have spare disk to do some tests. I guess I coud be able to fix this through parted / other tool by just changing the partition type / flag but I'm not 100% sure.

Here are the info about the disk :
