I've never been completely certain-- write precomp was used back in the days
of MFM and RLL devices, the landing zone was the track where the head was 
supposed to go when the disk was "parked", IDE disks "auto park" the heads off 
of the media area of the disk anyhow.

A sector on an IDE drive is, if I recall correctly, 512 bytes.  So your
980, 5, and 17 disk (roughly 83,000 sectors) would be about a 40 meg disk.
