  Hello,
 I wonder how I can make an 1:1 copy of a floppy, including the bad
 sectors on it... Plain dd fails with i/o errors.
 I tried ddrescue to make an image, and wrote the resulting image to
 another floppy, but it does not work :-(
 Background:
 I'ts about a floppy that came with a windoze software which stores a
 license. A backup of this key is what is needed...
 Is there another way doing this copy?
 Regards,
 Yves 
Did you try fdutils: ;-)
http://fdutils.linux.lu/
It has a nice fdrwacmd utility which allows to retrieve sectors and
ignore any CRC errors...

Alain
