Yes: it doesn't retry at all.

These are not retries, these are two separate attempts to access the
floppy. When a DOS call is issued to open a file on a floppy, DOS breaks
that into a series of accesses. That's what you see, I think.

I don't think I see this, but I use CWSDPMI. Did you try CWSDPMI
(although I don't think it matters)?
Also, what, if any, memory manager do you have installed on that machine?
And what version of DOS?
