You can pull a Model and Serial number via hdparm -i, but it's not as
easy to manipulate as a fixed-length MAC address.  That's why people
tend to use filesystem UUID's.

ATA8 at the moment looks set to add a true "MAC" or "WWN" type identifier
to each device.. Right now model/serial is not always unique.

WWN was added in ATA-7, AFAICS.

However, I've seen quite a few ATA-7 devices that do not bother to fill it in. I wonder if ATA-8 device firmwares will act with similar slackness. :)
