Using Linux I was trying to access an exfat partition that was created using the partition tool in Windows. Due to some improper shutdown issue I was not allowed access.

Then I took the brilliant decision of running ntfsfix on it

mint@mint:~$ sudo ntfsfix /dev/sda9
Mounting volume... NTFS signature is missing.

Attempting to correct errors... NTFS signature is missing.

Failed to startup volume: Invalid argument

Record 0 has no FILE magic (0x47aac24e)
Failed to load $MFT: Input/output error
Volume is corrupt. You should run chkdsk.

After this the partition in question, sda9, was being shown as NTFS. It was exfat before this step.

I did run chkdsk on the partition from Windows and got

C:\WINDOWS\system32>chkdsk f:
The type of the file system is NTFS.
Unable to determine volume version and state.  CHKDSK aborted.

I got access to another exfat partition(sda5) that was not put through ntfsfix simply by accessing the drive from a Windows machine but the newly NTFS partition wont open saying the 'partition is corrupted and unreadable'

So I feel marking the partition as exfat however ntfs-3g marked the partition as NTFS will give me back access to my drive.

Are there any non-destructive things I can try?
My top priority is to save the data on this disk.
