Thank you for the pointer to WinObj. (It also explained much which was
previously cryptic in the way the two os's handle devices and Net volumes as
well as the afore mentioned cdrom0 question).  I had been worried that
mounting the link to the drive letter,  might have bypassed blocks
accessible  by the block device link (as is the case with physicaldisk0 and
the drive letter).  I see now that this is not the case with the CDROM.

Thanks again
B. Dobrin
