To spoof hard drive SMART serial numbers at the kernel level:

  1. Attach a filter driver to \Driver\Disk or \Driver\Storport.
  2. Intercept IRP_MJ_DEVICE_CONTROL requests where IoControlCode == IOCTL_STORAGE_QUERY_PROPERTY.
  3. Set an IoCompletionRoutine and pass the IRP down the driver stack.
  4. In the completion routine, when the disk controller fills the STORAGE_DEVICE_DESCRIPTOR buffer, scramble the SerialNumberOffset string with randomized alphanumeric bytes before returning to userland!

Disk filter driver completion routine is the cleanest way to spoof disk serials across all Windows versions.
