How to get the hard disk serial number correctly?

NTDEV
1

I want to get the hard disk serial number. GetVolumeInfo() can get the volume serial number, but it would changed after formating the disk. How to get the physical serial number correctly?

So use pass through and send a SCSI INQUIRY. If THAT serial number changes
you ain’t talking to the same disk.

Hi,

if you want to do this in User Mode then you can either use WMI Win32_DiskDrive with Win32_PhysicalMedia or DeviceIoControl with e.g. IOCTL_CHANGER_GET_ELEMENT_STATUS, IOCTL_CHANGER_GET_PRODUCT_DATA, IOCTL_STORAGE_GET_MEDIA_SERIAL_NUMBER, maybe there are some more,…

The IOCTLs are not working with all kind of drives/devices, some only work on USB devices, you have to keep that in your mind,…

best
