Copying rev files like this most likely won't work.

To replay changes you've lost, you need to pretend to be a developer
making the changes again.
You need to use svn checkout to get a working copy, make the changes
which happened (and have been lost) in that working copy, and use
svn commit to commit the changes, thereby re-creating the missing
revision. Then load additional revisions on top using svnadmin load.
If you don't know exactly what changes were made in the lost revisions,
maybe you can interpolate the changes by looking at past and
future revisions around the time of the missing changes?
You were talking about changes made to binary files in
http://svn.haxx.se/users/archive-2010-06/0218.shtml so it can be
quite hard to recreate the changes.
Maybe you can get away with just omitting the missing revisions
entirely? Dump all revisions you are able to dump. For the first dump,
use svnadmin dump -r0:X (where X is the last good revision before the
first one that got broken by the disk failure). For any dump
of later revision use svnadmind dump -rA:B with the --incremental option
of svnadmin dump. Then try to load all the dumps in succession.
I'm not sure what you mean when you describe that loading a dump
file into a repository causes a single large revision to be created.
That doesn't make any sense to me. I've never seen this happen.
When this happens, what's the output of the svnadmin load command,
and what's the output of the svn log command? Maybe I'm misunderstanding
what you are trying to say? Please show the exact command you are using
for loading. In fact, it would really help if you could simply post a
transcript of all the commands you have tried running so far, and their
output, without explaining your interpretation of things. This should
help avoid misunderstandings. Based on such a transcript, we could ask
further questions and provide hints, and hopefully help you fix the problem.
