} Check dmesg (or /var/run/dmesg.boot). The serial number should show, e.g.:
} 
} ad8: 381553MB <Seagate ST3400633AS 3.AAH> at ata4-master SATA150

That's a model number, not a serial number.  

I'm not sure if there's a simpler way, but smartctl (from the smartmontools 
port/package) will display a disk's serial number.

[602] root at woodstock tmp$ smartctl -a /dev/ad0 | grep -i serial
Serial Number:    9QG386BV

There's probably a better way, but this should at least work.
