I doubt this is someone from the board.
This is probably just the drive cloning method -- taking a real 80 gig Phatnoise drive, buying a similar drive (note how it's specifically a Fujitsu drive ?) and using some tool to rewrite the serial number / drive ID info.
Some work with Google turns up a lot of crap, but it seems that in the end, that info is stored on a (less likely) EEPROM on the drive controller board or (more likely) on a reserved part of the drive, along with bad sector maps, etc.
The people who know about this stuff don't like to talk about it-- check this out for a great example:
