track -1, head 0, sector 19 contains the drive serial number as ASCII text. interesting.

track -2 contains the same 32 sectors on all heads. it seems to be 8051 code (02 is the LJMP instruction). i'm guessing this is the main drive operating code.

@tubetime Lot of drives had the firmware on hidden tracks. I am entertained that it's an 8051 though. The newer drives got much better CPU
