cygwin下执行dd命令总是提示"dd: writing to '/dev/sdx': Permission denied"如何处理?

答: 将命令中的/dev/sdx替换为对应设备的DeviceID

1. 如何获取对应设备的DeviceID?

在powershell下执行以下命令:
C:/> Get-WmiObject Win32_diskdrive

    Partitions : 2
    DeviceID : \.PHYSICALDRIVE1
    Model : Mass Storage Device USB Device
    Size : 3109978
    Caption : Mass Storage Device USB Device
2. 示例如下:

$ dd if=my-file.bin of=\.PHYSICALDRIVE1  (原来的执行命令为dd if=my-file.bin of=/dev/sdb)
