exFAT support on macOS seems to have some bugs because my external drives with exFAT formatting will randomly get corrupted.

If Disk Utility is unable to repair, consider trying this:

1. In Disk Utility, ensure that the drive is not mounted, eject it if it is mounted.
2. Use diskutil list to find the right drive id.
3. You want the id under the IDENTIFIER column, it should look like disk1s1
4. Run sudo fsck_exfat -d <id from above>. eg sudo fsck_exfat -d disk1s3
5. -d is debug so you'll see all your files output as they're processed.
