第一步先查看硬盘的信息使用如下命令行

diskutil list

输出内容参考

/dev/disk0 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *251.0 GB disk0 1: EFI EFI 314.6 MB disk0s1 2: Apple_APFS Container disk1 250.7 GB disk0s2/dev/disk1 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +250.7 GB disk1 Physical Store disk0s2 1: APFS Volume Macintosh HD - 数据 184.4 GB disk1s1 2: APFS Volume Preboot 84.5 MB disk1s2 3: APFS Volume Recovery 528.5 MB disk1s3 4: APFS Volume VM 3.2 GB disk1s4 5: APFS Volume Macintosh HD 11.1 GB disk1s5/dev/disk2 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk2 1: EFI EFI 209.7 MB disk2s1 2: Microsoft Basic Data Elements 999.8 GB disk2s2

第二步/dev/disk2是移动硬盘，使用挂载命令直接挂载就行如下

sudo fsck_hfs -fy /dev/disk2在执行装载命令之前先执行上边这行命令sudo diskutil mount /dev/disk2
