I retrieve a USB flash drive serial number by means of ioctl HDIO_GET_IDENTITY as described here.
Yet, for some flash drives there is no serial (for example my SanDisk Cruzer).
Why some drives don not return a serial number?
a) HDIO_GET_IDENTITY not implemented in driver ?
b) They just don't have one ?
c) Other ? (what?)Is there a specification (like IEEE) that describes where and how the serial number is stored inside the flash drive?
