    dd command used to write image file on destination disk assuming destination disk is floppy.

    wanted to format it. I formatted it as FAT32 now I can successfully mount
    it on my RH 7.1 Linux system again.

    Now I just have to figure out what happened when I did the 'dd' command. I
    copied over a RH boot.img which I believe is a fat filesystem and a
    drvnet.img which is a ext2 filesystem. I tried to mount with a -t option
    and the type of filesystem but kept getting errors.
