Nope.  All requests in DW use LSN, just linear sectors from 0 to
whatever.  There is no concept of tracks, sides, etc.  Sorting that
type of thing out is the responsibility of the CoCo side driver.  If
there is a restriction to 35 track disks in DECB, that's something
imposed by HDBDOS's DW driver.  Probably because of the multi-disk
partition scheme they need to all be of identical size.
