winapi - Does GetVolumeInformation() returns a unique volume serial number? -


the documentation getvolumeinformation() says:

this function returns volume serial number operating system assigns when hard disk formatted. programmatically obtain hard disk's serial number manufacturer assigns, use windows management instrumentation (wmi) win32_physicalmedia property serialnumber.

does windows assigns unique volume serial number, or multiple machines have same volume serial number?

the volume serial number dword. there 232 different possible values of dword. therefore stands reason since there finite number of possible values, , unbounded number of volumes in world, there multiple volumes sharing same serial number.
