我可以这样检测驱动器：
cat /proc/partitions
major minor #blocks name
8 0 2930266584 sda
8 1 512000 sda1
8 2 372669440 sda2
8 3 409600000 sda3
8 4 1364700160 sda4
8 16 1953514584 sdb
8 17 1 sdb1
8 21 1953506520 sdb5
这是sdb
但问题是，当我尝试列出它时，fdisk它在这里不起作用，结果是：
bash-4.2# fdisk -l

同样的情况发生在gdisk
有谁知道是什么问题吗？
其他详细信息： 它在 Windows 7 上工作正常。lsusb 返回 HD 它是最后一个“Samsung Electronics Co.”....
