You shouldn't "expect" this in any way shape or form.  The device
numbers are not consistent, and are known to change depending upon lots
of reasons (AHCI disabled/enabled, another ATA controller in place, SATA
in "compatible" mode or "enhanced" mode, etc. etc.).

Thus, never expect the adX devices to "start with 0".
