折腾：
【未解决】Mac中无法识别exFAT的外接移动硬盘
期间，前面尝试用fsck_exfat修复出了问题的exFAT硬盘，未果。
现在换diskutil试试。
试试mount：
xxxdeMacBook-Pro:~ xxx$ diskutil mount disk3s2
结果没反应
然后超时了：
xxxdeMacBook-Pro:~ xxx$ diskutil mount disk3s2 Volume on disk3s2 timed out waiting to mount
然后去：
xxxdeMacBook-Pro:~ xxx$ diskutil repairVolume disk3s2 Started file system repair on disk3s2 内容备份2 Repairing file system Volume is already unmounted Performing fsck_exfat -y -x /dev/rdisk3s2 File system check exit code is 1 Restoring the original state found as unmounted Error: -69845: File system verify or repair failed Underlying error: 1: Operation not permitted
然后kill掉fsck后可以去修复了：
aturlingdeMacBook-Pro:~ xxx$ ps aux | grep fsck root 2635 98.2 0.5 4333648 19012 ?? R 7:35下午 6:54.89 /System/Library/Filesystems/exfat.fs/Contents/Resources/./fsck_exfat -y /dev/rdisk3s2 xxx 2669 0.0 0.0 4286184 916 s004 S+ 7:43下午 0:00.00 grep fsck xxxdeMacBook-Pro:~ xxx$ sudo kill -9 2635 Password: xxxdeMacBook-Pro:~ xxx$ diskutil mount disk3s2 Volume 内容备份2 on disk3s2 mounted xxxdeMacBook-Pro:~ xxx$ diskutil repairVolume disk3s2 Started file system repair on disk3s2 内容备份2 Repairing file system Volume was successfully unmounted Performing fsck_exfat -y -x /dev/rdisk3s2 Checking volume Checking main boot region Checking system files Volume name is 内容备份2 Checking upper case translation table Checking file system hierarchy [ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ]
然后等待，结果时间太长，而取消了。
然后去换用win去修复：
