I've never heard of that but it's most likely a firmware hack. Maybe Windows only reads how much space is being used, and checks the drive information for total space.
Its defenitely in the firmware.
Windows doesn't have direct access to any media.
Its always going to go through the controller for the media.
Hack the controller , be it the microprocessor on memory cards or the drive controller on a hard drive and you can make it report whatever you want.

You just need to change the ID the drive reports to Windows, and geometry information, and create a big partition on it. As long as you don't try to write to that area of the partition, it all works just fine
