C ++ hardware information to obtain the hard disk serial number

C ++ hardware information to obtain the hard disk serial number

This section describes how to obtain the serial number of a hard disk, not the serial number of a hard disk partition. The core is throughDeviceIoControlInterface to obtain the version and data information of the hard disk.

Simple.
