Unfortunately I don't seem to have diskio.h and/or definitions for STORAGE_IDENTIFICATION or IOCTL_DISK_GET_STORAGEID.

I want to be able to read a unique identifier from a USB mass storage device and compare that to an encrypted file saved on the USB mass storage device which contains the same value. If the values match, then additional features will be activated in my software. If they don't match (the encrypted file has been copied to a different USB mass storage device) then the features won't be activated. Simple anti-piracy.

Correspondingly, I would need to be able to obtain the same identifier from Windows XP in order to create the encrypted file.

The actual meaning of the ID doesn't matter... device serial number, volume serial number, etc... as long as its unique to that formatted USB device.

Any pointers?
