Not with modern DASD, AFAIK. Tracks, cylinders, etc are just logical constructs. The 'front' of a volume could appear just about anywhere on the physical disk.
Except for some potential logical fragmentation issues, why do you care?
Virtual disk 3390-27 is still real from z/OS point of view. Usage map is
very real. However IMHO it does not justify usage of ABSTR, doesn't
matter how real or virtual is the disk. Or course - from the other hand
- there is nothing shameful in using ABSTR. <g>
