Mac不识别被强制拔出过的移动硬盘_if you think the volume is supported but damaged,

移动硬盘是ExFat格式的，之前在Mac上可以正常使用，后因为在大疆无人机遥控器上插拔后Mac插入不识别，硬盘工具无法挂载。

1. diskutil list // 查看对应移动硬盘磁盘号
/dev/disk2 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *1.0 TB     disk2
   1:               Windows_NTFS LENOVO_USB_             1.0 TB     disk2s1
 
2. sudo diskutil mount /dev/disk2 // 尝试挂载
 Volume on disk2 timed out waiting to mount //失败
 
3. sudo fsck_hfs -fy /dev/disk2  // 修复处理
** /dev/rdisk2 (NO WRITE)
   Executing fsck_hfs (version hfs-522.100.6).
volumeType is 0
/dev/rdisk2 0000:  0000 0000 0000 0000 0000 0000 0000 0000       |................|
. . .
/dev/rdisk2 01b0:  0000 0000 0000 0000 460a 1659 0000 0020       |........F..Y....|
/dev/rdisk2 01c0:  2100 07fe ffff 0008 0000 0058 7074 0000       |...........Xpt..|
/dev/rdisk2 01d0:  0000 0000 0000 0000 0000 0000 0000 0000       |................|
. . .
/dev/rdisk2 01f0:  0000 0000 0000 0000 0000 0000 0000 55aa       |..............U.|
 
4.sudo diskutil mount /dev/disk2 // 再次尝试挂载
Volume on disk2 failed to mount
Perhaps the operation is not supported (kDAReturnUnsupported)
If it has a partitioning scheme, use "diskutil mountDisk"
If you think the volume is supported but damaged, try the "readOnly" option
 
5. sudo diskutil mountDisk /dev/disk2 //根据提示更换命令
Volume(s) mounted successfully  // 大功告成
