Id suggest maybe 4 heads and a lot more sectors.
Just find out how many platters it has and x 2 for maximum head
numbers. I have never seen more than 3 platters in a 'domestic' 
type of drive. thus maximum 6 heads.

The raw readings are still translated by the drive to get around the
archaic ide address field limitations.

For a bit more information, go to http://www.quantum.com
and read the spec sheets on the new fireballs. Pretty Eye opening.
