This code makes three attempts at obtaining the serial number:
- Using
IOCTL_STORAGE_QUERY_PROPERTY.
- Using
SMART_RCV_DRIVE_DATA.
- Using
IOCTL_SCSI_PASS_THROUGH.
This code works for me on 64-bit:

Next

EDIT - I've changed the main method to display the results of each attempt for comparison. This will hopefully illustrate how hit and miss these techniques can be.
