}No error messages while making the copies (80 records copied message only),

Your best bet for copying Xenix diskettes is with the Xenix utility
"diskcp".  The DOS "DISKCOPY" command really only works with DOS
diskettes.  To use "diskcp", insert the diskette you want to copy into
your floppy disk drive and enter the following command:

           diskcp -f -s -96

This will copy a 1.2 MB diskette and format the new diskette before
coping the new files to it.  For other disk sizes, enter the command
"diskcp -u" which will give you all the options for diskcp.
