In our application,
We need to read some Vital Product Data
before we issue the Start Unit Command
(to spin-up the disk drives).

I noticed that the serial number field
is returned with all zeroes when the drives
are not spun-up.

I always thought that the Inquiry data must
always be available and valid from NVRAM
(including VPD).
