I tried to mount /dev/da0s1 by using mount_msdosfs /dev/da0s1 /mnt, and I got the kernel panic. I tried another broken usb drive, the result is the same, kernel panic. I also tried it on Linux using "mount -t /dev/sdb1 /mnt", no panic. Does it make sense that mounting broken USB drives would cause the kernel panic? Any idea how to solve this issue? thank you. Regards, Dave.
