Actually, that's exactly what looks like is happening... I know that the 
serial number should be in the VPD at 0x80 (with a little more info at 
0x83) but I just can't seem to read it. Admittedly my experience reading 
devices directly is quite slim though, so here's to hoping I am missing 
something. :p

In the mean time, I am now trying to figure out another way of uniquely 
identifying a given hard drive other than it's serial number. *sigh* Do 
you know the reason behind this not being available? Like, I can read 
the serial number off my digital camera and it's a vfat partition over a 
USB 1.1 link...
