The hdparm manpage says about -i, that it obtains info "obtained from the drive
at boot time, if available". The "if available" says to me that it doesn't have
to return the info, and that it isn't always expected to. Also, given that -I
works, which is info obtained from the driver directly, I think things are
working as expected, and that there is no bug.
