I also encountered that issue using TD02IMD last year with some of the
HP-85 series software images, for example this one:

I think the issue is that the Teledisk images were built including some
additional sectors that are essentially garbage and could be ignored.
My solution at the time after spending some time looking at this was to
rebuild TD02IMD from the source code available on Dave's site to ignore
these extra garbage sectors that were cause the fatal errors.
I'd have to look back at my notes on this to remember exactly what I did
here.
It would be a useful project to go through the Teledisk images on the HP
Museum site and convert them all to ImageDisk format.
Indeed, I was hoping someone might have already done this :-)
I am not sure though if I should expect the disk not ready error when
Teledisk writes the last track to the physical floppy. It would seem a
reasonable method to convert via floppy, ie Teledisk -> Floppy -> IMD, but I
am not sure if this is really working for me at the moment.

Have you tried using Dave's TD02IMD program to directly convert the
Teledisk .TD0 to .IMD files?
Sorry I forgot to mention that I tried that and it failed with an
error about different sector sizes on the same track.
