I guess so.  Now the question is, what will give me a bit for bit copy,
bad sectors and all?  Currently testing 'dd conv=noerror' on a dodgy
floppy.  Next test is 'dd conv=noerror,sync' to see if that gives a
matching size of image.

So, 'dd conv=noerror,sync' on a dodgy floppy disk gives me a 1.44Mb image
while 'dd conv=noerror' on the same floppy gives me a 1.1Mb image.  CD is
currently working through a 'noerror,sync' run.  Let's see what that
produces.
