I have a WesternDigital external(usb3) 5TB hdd that keeps mounting as readonly on the mac every time I reconnect it.
The drive was formatted ExFat with diskUtil and is only about a month old.
sudo fsck_exfat -dy /dev/rdisk3s1 several times, I keep getting results like this.
0 clusters were marked used, but not referenced 0 clusters were marked used and CLUST_BAD 21 clusters were marked free, but referenced ** Rechecking main boot region. ** Rechecking alternate boot region. Write offset = 0x000006040000 length = 0x040000 fsck_exfat: Couldn't write 262144 bytes at offset 100925440, errno 9: Bad file descriptor
I can remount the drive with
sudo mount -u -o rw /Volumes/Clients and it seems to work mostly fine (found one corrupt file, but since theres tens of thousands of files, I cant check them all).
How do I troubleshoot the drive further?
