So what? The HD160JJ is not an F3 drive.

The same statement, if applied to the HD160JJ, would have been ...
"Notice that the second last character in the model numbers for the P80SD series increases in ASCII value as the capacity increases."

SpinPoint F3 and SpinPoint F2EG are NOT "families" . It's like saying "caviar blue" or "caviar green" for another brand.
I don't see anywhere where I've used the word, "family".

Examples :
SV1021H (V11+) CAN be (but they won't tell you unless you open it OR send certain techno commands) a SV2042H with disabled head... :mrgreen:
The OP appears to be interested in the "HD" drives. The "SV" model nomenclature is obviously different, therefore the "HD" and "HM" interpretations do not apply in this case. So why bring it up?

HD160JJ can come in TWO different version with same model number from two sub-families of P80 (THESE are the technical families, not generic commercial "F3") - totally different drives with totally different microcode (respectively WU100-4x and ZM100-4x).
HD161HJ , this time belonging to same FAMILY , can come in two flavor with different chip on board, one has GF100-1x the other GF100-xx firmware. Nevertheless you may find HD080HJ that has been made from HD161HJ ... and you get it when you open it :mrgreen:
So what? One drive may have additional disabled heads, but the model number reflects the enabled heads.

If the 3rd number was in pure hypothesis related to the head number, HD080 would have had 0 heads (the perfect HDD with no moving parts, maybe :lol:).
What are you talking about? The HD080HJ has 2 heads.
