I know there is a verify /v option for copy in dos.  IE "copy /v c:test.dat
a:".

It detect a problem by reading back the new file and comparing with the
original.

I think the c64 drives did a comparison 5 times so they were extra slow
until someone came up with a way to turn verify off.

Perhaps

Subject: [EE]: Do floppy drives have any error checking/correction?


I'm wondering about the data integrity of sensitive data files I'm moving
using floppies. If there is an error due to a bad sector, physical problem
with the disk, or any other factors, will the error/lost data be detected?
If so, how does the drive accomplish this detection?

Thanks!
