Floppy error and omisions can be caused from incorrect copying = procedures for=20 example tell copy that all files are to be transfered as ASCII files can = cause=20 problems, but that can be rules out. If some sort of cache system is = used this=20 can also occur(UNIX users will note this when copy from a DOS partition = over the=20 network to a UNIX fs). But that does not seem to be the problem.

Check the Floppy drive using Nortons or some other hardware testing = software.
