No, I don't think that is true. What is true is that recent versions of SIMH
will create full size container files for disk containers. But sufficiently
old versions did not, so it is not too strange to run into, say, an RK05 image
that's shorter than 4800 blocks.
But those normally work; all that happens is that reading too far either gives
you zeroes or a read error, I don't remember which. Since the blocks were
never written they should be marked as unused in the file system and nothing
will read them, so that's fine.
If there's an unused track at the start of a SIMH image file and in your copy
that was missing, that's a different case. Is that the issue?
Or is the RX02 emulation different from regular disks?
