As I  understood David's American language <g>, he meant security  
exposure, not data recovery possibility. In other words, ZAP can be used  
(or cannot be - that is the question)to disclose data, unformatted, in  
sysprint, etc.  So there is risk a of "quick erase".

Regarding  to the original question: I don't know whether ZAP can be used 
for that,  but I believe, it is protected by RACF DASDVOL/GDASDVOL class 
profiles. At  least VTOC is.





IMASPZAP can be used to display and/or alter any data which the system's  
security rules allow, including allocated data sets that belong to other  
users.  
If you want to alter data inside a VTOC, I believe that a WTOR is  sent to 
the master console.
