exFAT volume often gets corrupted

Was on the verge of spending between $400 to $2000 in data recovery services

Googled 'Corrupt EXFAT partition'

Found this thread.

Ran the 'fsck_EXFAT' command [note that I had to select the 'windows' EXFAT partition, it didn't work on the 'Apple' one, used the -d option, thousands of lines of file entries flashed by.

It did ask me 'mark volume as clean' and I wondered if this would delete the disk so exited Terminal

Rebooted, then ran Disk Utility First Aid . It did take a while and I wondered if it had hung, but it was a 4TB drive .

Confirmed it fixed a few boot records.

Note that Apple Technical support will not help out with this particular FSCK etc command, I called them wondering about it and they said that it's out of bounds for them.

My gratitude knows no bounds to 'NeoAmiga' and the rest of you !

El Capitan 10.11.6 on 2012 MacPro with Win7 Bootcamp partition.

chkdsk d: /F

This helped me. I used the above command on a windows machine and when i connected back to MAC, my drives reappeared. Thanks so much

NEO_AMIGA, thank you very much.

Important part for my LaCie Rugged (after Sierra update), was that you don't run command on disk it self but it identifier.

So my command was:

sudo fsck_exfat -d disk2s2

and that asked that same question as you all said, after that I ran First aid in DU, which said it cannot repair disk, but unplug and plug did it, I saw it again.

Thank you a lot, I knew I didn't lost files, as I have it in RAID 1, and didn't do a thing, just updated Sierra, but didn't expect exfat to act like this.

Thank you one more time.

Thanks NE0.. your a lifesaver. 🙂

NYU student here who lost academic materials 😝

But recovered 😀

I have same problem, how did you resolve it?

tnx

When I use the sudo code, which password is it asking for? because I'm not the admin nor do I have permissions for the computer I'm on. But I do have permissions for the drive.
