As I recall, on VMS a disk is a file; a file spec consisting only of a device
name accesses that device. So unlike some other operating systems where
special syscalls are needed for raw disk access, on VMS I would expect it to be
just a matter of accessing DUA1: or whatever.
I haven't done this in ages, but this is what I recall from when the question
came up in the context of my FLX program (RSTS file I/O).
