I thought I remembered reading something about different parameters
for diskettes under DOS 3.1 as compared to 2.1, but I cannot find the
information.
     
I have a half dozen floppies with some files that cannot be read with
3.1, but are copied fine with 2.1.  Same physical drive.  These are
Tandon or IBM 360k full-height (antique) drives.  Using vanilla DOS
COPY command.  A Toshiba half-height drive reads the same files fine.
     
Errors are "Data error reading . . ." and "Sector not found . . .".
     
The drives run slower under 3.1.  Does anyone have information about
patches that may help?
     
Thank you in advance for any assistance.
