But if RT-11 uses this device driver even when reading the disk without
trying to handle it as an RT-11 file system, then the RT-11 device
driver can't be used at all if you want to read foreign packs.

There's a .SPFUN to bypass RT's private bad-block replacement (yes the list
is in block 1), so you can easily write a small program to do the copy, but
I'm 99% sure COPY/DEVICE will just use .READ so, bad news.

Writing a stand-alone program to copy RLs would be straightforward, if you
wanted to be done once and for all.

Yes, you could easily do a trivial copy program standalone.
However, we still have the problem with any actual bad block mismatches between the two packs.
There is no real good solution here. Find error free packs is all I can say.

As for the original question, under RSX, there are several ways, as have already been mentioned.
