Nothing wrong with that, mind you.

Nevertheless, what I wrote is what RT-11 COPY does.
Actually COPY/DEV under RT-11 is commonly used,
especially for non-RT-11
packs. I can't remember what RSX does, but RT-11 /does/ deal with the
bad block table, by not copying the last track, and copying remapped
blocks.
But that don't make sense. You cannot just move one block somewhere else
because it is bad on the target device. Or just ignore a block because
it is bad on the source device. And "remapped" must be something very
local to RT-11. RSX do not remap
any blocks. A block that is bad, is bad. It is still there.
Well, yes, it's still bad, and still there, but all the RT-11 utilities
use the substitute block.
