MBRFormat 似乎不是其文件系统的有效卷名

Question

我使用的是 macOS Mojave 10.14.6。我正在尝试将我的 USB 重新格式化为 FAT。我收到此错误MBRFormat does not appear to be a valid volume name for its file system。这是什么意思以及如何解决？为什么文件系统显示“无”？

MBRFormat does not appear to be a valid volume name for its file system

已经是FAT格式了吗？

/dev/disk5 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *8.0 GB     disk5
   1:       Microsoft Basic Data MyDrive                 7.8 GB     disk5s2

Answer 1

THE_NAME 应该大写。

sudo diskutil eraseDisk FAT32 "THE_NAME" MBRFormat /dev/disk5

Answer 2

您在格式后缺少（新）卷名

sudo diskutil eraseDisk FAT32 THE_NAME MBRFormat /dev/disk5
