Recovery with a disk that wasn't quickly pulled offline can be dicy.  
Blocks get reused.

If you want to learn how OpenVMS works, or if you have no budget for 
somebody to look at this, yes.

If you want to learn more about OpenVMS, this is one good way how.

Nope.

You either get (enough of) your data back, or you don't.

If you don't get your data back, then you're out either the money you 
spent on the recovery, or the time you spent performing the recovery 
yourself, or both.

If you did your own recovery work here, then you've learned more about 
the details involved than you'd ever learn from comp.os.vms or from 
asking questions in general.

Few folks in this situation are willing to pay, irrespective of the OS 
and the platform and the particular trigger for the deletion.
