I've been using MSDOS since version 2.0, and I've never had a data
error like that.  I've occasionally had disk errors which result in
an error prompt (the traditional "Abort or Retry?" type things),
but never data corruption in a file which could be read from the floppy.
And I've transferred many gigabytes to and from floppy, still averaging
several files over 500K per week (it's my transfer mechanism between home
and work).

Note: I've never used DR-DOS or Novell DOS, and I'm still not running
OPENDOS because of incompatibilities.  If this is an OPENDOS error
then it's very serious.

You say "adding other programs" - do you mean TSRs or just running programs?
Which other programs?

Any of those, plus whatever "other programs" you're running.  I assume 
you've tried using different floppies as well...

Well an Entomology department sound like the place to find bugs, no?  <g>
