VM/ESA Version 1 Release 2. It was the result of FIN APAR VM57616 (against VM/ESA V1R1), which described a problem with MDC and minidisks that overlay system areas. Abends were the result. The documentation for MDC says "don't do that", but it would thought some people might miss that fine print and in the interest of family harmony, we added code. A look at that code reveals that any minidisk that starts on cyl 0 (even if it isn't fp mini) is *exempt* from this check. So be very careful if you have partial overlays. Ensure MDC is OFF for that minidisk. Alan Altmark z/VM Development IBM Endicott
