    Lots of moving parts. I pine for the heady daze of IML partitions...

    Heck no, it is nowhere near done...

    So, I am quite kontuzed.

    So, we have a DBA-ESDI drive. FAIK, it is a Physical CHS device.

    IBM defines it as Cylinders [Data, Spare, CE, Primary, Secondary, and
    Factory Defect]. So, in some drives, there are 33 sectors in a track.

    But... how many tracks in a cylinder?
