注意 - 执行此活动将清除U盘上的所有内容 步骤1 插入U盘 步骤2 查找有关Mac上所有磁盘/驱动器的信息打开终端,使用diskutil list命令查找有关所有磁盘的详细信息: $ diskutil list /dev/disk0 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_CoreStorage Untitled 249.9 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 4: Apple_CoreStorage disk2 749.2 GB disk0s4 5: Apple_Boot Boot OS X 134.2 MB disk0s5 /dev/disk1 (internal, virtual): #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS disk1 +249.5 GB disk1 Logical Volume on disk0s2 21111116-B31C-41F0-A0E0-511111183735 Unlocked Encrypted /dev/disk2 (internal, virtual): #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS disk2 +748.8 GB disk2 Logical Volume on disk0s4 02222220-CDFD-47D1-85C7-F222222867E6 Unlocked Encrypted /dev/disk3 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *750.2 GB disk3 1: Windows_NTFS Secure_HDD 750.2 GB disk3s1注意:disk3是我想要创建两个FAT32分区的那个。 注意:disk3格式为NTFS。 您可以先使用Mac Disk Utility擦除磁盘,然后使用正确的格式重新格式化。 注意:disk3目前无法分区。 看到灰色的图标。 在练习结束时,您将能够对其进行分区。 步骤3 使用Mac 自带的磁盘工具擦除U盘使用Mac 自带的磁盘工具擦除U盘,选择ExFAT格式 使用下面的命令,擦除U盘 $ diskutil eraseDisk JHFS+ $ diskutil eraseDisk JHFS+ Secure_HDD disk3 Started erase on disk3 Unmounting disk Creating the partition map Waiting for partitions to activate Formatting disk3s2 as Mac OS Extended (Journaled) with name BlackDrive Initialized /dev/rdisk3s2 as a 931 GB case-insensitive HFS Plus volume with a 81920k journal Mounting disk Finished erase on disk3 步骤5 U盘分区(disk3)现在你可以用苹果自带的磁盘工具对U盘进行分区了。 如果报错,例如: MediaKit reports not enough space on device for requested operation. 那么运行下面的命令: $ diskutil unmountDisk force disk3 Forced unmount of all volumes on disk3 was successfulWrite zeros to the boot sector: $ sudo dd if=/dev/zero of=/dev/disk3 bs=1024 count=1024 Password: 1024+0 records in 1024+0 records out 1048576 bytes transferred in 0.516867 secs (2028716 bytes/sec)Remove the disk (detach the USB) and plug it in.
