For copying FILES, that shouldn't be a problem.  For making IMAGES of the 
disks that would be.

For copying FILES, you would only be accessing the DIRectory sectors, and 
the tracks following them, with no need to even look at boot sector or 
system track(s).

But, that's still a useful warning, to NOT try to tell whether the disk is 
FM or MFM based on track 0!
