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?
